# Orihako PDF

> 43 free PDF tools – merge, split, compress, redact, OCR, fill and sign, convert and more – that run in your browser without uploading the file. Part of Orihako (https://orihako.com/), nine browser tools that work on your files on your own device and never upload them to a server (Send hands a file straight to the other person's device).

This is the long version of https://pdf.orihako.com/llms.txt. It is written when the site is built, from the same words the pages show.

Free: every PDF tool, one file at a time. With a Pass: batches, saved steps; desktop agent with Pro or Business.

The page for AI assistants and agents: https://pdf.orihako.com/agents/ (ja: https://pdf.orihako.com/ja/agents/, fr: https://pdf.orihako.com/fr/agents/).

Steps and Back: each run is a step of the person's work. After going on to another tool or leaving the page, Back, Forward or a reload puts the files, the settings and the result back as they were, without running again; a step left by going another way stays under "Steps you left". Each step's files are kept in this browser for 24 hours (orihako.com's storage on this device, never uploaded to a server); "Close this work" deletes them, and "keep no step results" on https://orihako.com/history/ turns keeping off (leaving redaction or signing work then asks first). Going back is free; going on to a second PDF tool with the result needs a Pass.

## Tools

### Merge PDF

https://pdf.orihako.com/merge/ (ja: https://pdf.orihako.com/ja/merge/, fr: https://pdf.orihako.com/fr/merge/)

Combine two or more PDFs into one, in the order you choose.

Also runs in the desktop agent. Callable from other sites through /embed/ as "merge".

How to:
1. Drop two or more PDF files, or click the box to choose them.
2. Put them in order with the arrows. Click a thumbnail to leave a page out.
3. Press Run, then download the merged PDF.

Questions:
- Q: Is there a limit on the number of files?
  A: Up to 200 files and 500 MB in total per run. Merging happens in the browser's memory, so on a phone about 200 MB in total is a sensible ceiling.
- Q: Are bookmarks kept?
  A: Yes. Each file's bookmarks are kept, and you can also add one bookmark per file.
- Q: Can I merge a password-protected PDF?
  A: Yes. When you drop a protected PDF, a password box appears right below. Type the password and merge as usual.

### Split PDF

https://pdf.orihako.com/split/ (ja: https://pdf.orihako.com/ja/split/, fr: https://pdf.orihako.com/fr/split/)

Cut one PDF into several files by page ranges, or one file per page.

Also runs in the desktop agent. Callable from other sites through /embed/ as "split".

How to:
1. Drop one PDF file.
2. Type one page range per line, for example 1-3 and 4-. Leave it blank for one file per page.
3. Press Run, then download the parts one by one or as a ZIP.

Questions:
- Q: How do I extract just one page?
  A: Type that page number alone, for example 5. You get one file with that page.
- Q: Can one range overlap another?
  A: Yes. Each line is independent, so 1-3 and 2-5 give two files that both contain pages 2 and 3.
- Q: What does the ZIP contain?
  A: Every part, named after the original file with a number. It is built in your browser too.

### Compress PDF

https://pdf.orihako.com/compress/ (ja: https://pdf.orihako.com/ja/compress/, fr: https://pdf.orihako.com/fr/compress/)

Make a PDF smaller, especially one with photos, with almost no visible change. Handy for email and upload limits.

Caution: How much smaller a file gets depends on what is inside, and some files hardly shrink. Strong lowers photo quality, so keep Standard for printing.

Also runs in the desktop agent. Callable from other sites through /embed/ as "compress".

How to:
1. Drop one PDF.
2. Pick balanced (recommended), lossless, or strong.
3. Press Run and download the smaller PDF; Orihako shows the size before and after.

Questions:
- Q: Will my PDF look worse?
  A: Balanced only adjusts large photos, to a quality that still prints well; text and lines are untouched. Lossless changes no quality at all. Strong lowers photo quality further, for sending by email.
- Q: Why did the file barely shrink?
  A: Some PDFs are already compressed, or contain mostly text, which is small to begin with. Orihako never makes a file bigger; if nothing can be saved you get the original back.
- Q: Is there a size limit?
  A: Up to 500 MB per file. Your files are never uploaded, so there is no waiting, but large files depend on your device: on a phone about 200 MB is a sensible ceiling, and closing other tabs helps.

### Images to PDF

https://pdf.orihako.com/images-to-pdf/ (ja: https://pdf.orihako.com/ja/images-to-pdf/, fr: https://pdf.orihako.com/fr/images-to-pdf/)

Turn photos and scans (JPG, PNG, iPhone HEIC and more) into one PDF, one image per page.

Also runs in the desktop agent. Callable from other sites through /embed/ as "images-to-pdf".

How to:
1. Drop one or more images. Put them in order with the arrows.
2. Choose the paper size and margin; the preview shows the first page.
3. Press Run and download the PDF.

Questions:
- Q: Is the image quality reduced?
  A: No. JPG files go in as they are and PNG files are stored without loss. HEIC and other formats are converted on your device first.
- Q: What does "image size" mean for the paper?
  A: Each page takes the size of its image, so nothing is scaled. A4 and Letter fit the image inside the margins instead.
- Q: Can I use iPhone photos (HEIC) or WebP?
  A: Yes. Besides JPG and PNG, it takes HEIC, WebP, TIFF, GIF, BMP and AVIF, converted on your device.

### PDF to images

https://pdf.orihako.com/pdf-to-images/ (ja: https://pdf.orihako.com/ja/pdf-to-images/, fr: https://pdf.orihako.com/fr/pdf-to-images/)

Save each page of a PDF as an image, at the resolution you choose.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "pdf-to-images".

How to:
1. Drop one PDF file.
2. Choose PNG or JPG and the quality and, if you want, the pages.
3. Press Run. Download the images one by one, or all of them as a ZIP.

Questions:
- Q: Which quality should I pick?
  A: Standard for screens, High for printing, Light for small previews. Higher quality means larger files.
- Q: PNG or JPG?
  A: PNG keeps every detail and suits text and diagrams; JPG is smaller and suits photos.
- Q: Is there a page limit?
  A: Up to 200 pages per run; choose the pages for longer files. Speed depends on your device.

### Black out (redact)

https://pdf.orihako.com/redact/ (ja: https://pdf.orihako.com/ja/redact/, fr: https://pdf.orihako.com/fr/redact/)

Paint black boxes over words or areas; the pages under the boxes become pictures, so the text is truly gone.

Caution: The search only finds text the PDF holds as text; pages without text can be read first, but reading can miss words. Names, logos and handwriting are not found automatically, so draw over them. Open the result and check that nothing was missed.

Browser only: the desktop agent sends the person to this page.

How to:
1. Drop one PDF. Its pages appear at reading size.
2. Choose Find automatically (e-mail addresses, phone numbers, addresses, ID numbers) and/or Type words. What is found shows as dashed boxes on the pages and in the list: click one to leave it out, click again to put it back. Drag on a page to draw a box, a pen line or a thick highlighter line over anything else; click it to move it, drag a corner to resize it, press Delete to remove it, Ctrl+Z to undo.
3. Press Run. Pages with a box become pictures with the boxes painted; the finished file is then checked, and a report says whether anything is left.

Questions:
- Q: Is the text really gone, or just covered?
  A: Gone. A page with a box is replaced by a picture of itself with the box already painted, so there is no text object left to select, search or copy on that page. Pages without a box keep their text.
- Q: Can I search the file afterwards?
  A: The blacked-out pages are pictures. To make them searchable again, run Text recognition (OCR) on the result, or chain both in the workflow.
- Q: Does the word search find everything?
  A: It finds the words the PDF contains as text, ignoring case, and the kinds of data you ask for. Pages with no text (scans) can be read first: choose "Read the words on them first". Logos and handwriting are still not found: draw over them.

### Remove author info

https://pdf.orihako.com/remove-metadata/ (ja: https://pdf.orihako.com/ja/remove-metadata/, fr: https://pdf.orihako.com/fr/remove-metadata/)

Remove the hidden author name, title, dates and software name from a PDF before you send it.

Caution: Removes the title, author, software and dates stored in the file, what a camera wrote into its photos (such as where they were taken), comment authors and dates, attached files and scripts that run by themselves. It does not remove names written on the pages, what a photo shows, or what was typed into form fields.

Also runs in the desktop agent. Callable from other sites through /embed/ as "remove-metadata".

How to:
1. Drop one PDF file.
2. It starts as soon as the file is in. To keep attached files, choose Keep in the folded settings.
3. Download the cleaned PDF. Your PDF app's document properties will show the author and title empty.

Questions:
- Q: What exactly is removed?
  A: The document information (title, author, subject, keywords, software and dates), the hidden records apps leave behind, what a camera writes into a photo (where it was taken, the model, the owner's name), comment authors and dates, page thumbnails, attached files and scripts that run by themselves. A list of what went is shown when it is done. Page content, links, form fields and the words of comments are untouched.
- Q: Does it remove text or images on the pages?
  A: No. Visible content is not touched. To hide text on the page for good, use Black out.
- Q: Can a viewer still tell which software made the file?
  A: The software field is gone. The look of the text can still hint at the source, as with any PDF.

### Check before sending

https://pdf.orihako.com/leak-check/ (ja: https://pdf.orihako.com/ja/leak-check/, fr: https://pdf.orihako.com/fr/leak-check/)

Before sending a PDF, one press answers "can I send this?": hidden text, author details, comments, earlier versions, personal data in the text, whether it has a password, attached files and scripts. Each thing to fix comes with the tool that fixes it.

Also runs in the desktop agent. Callable from other sites through /embed/ as "leak-check".

How to:
1. Drop the PDF you are about to send.
2. Press Run: the pages are drawn to find text that does not show, the text is searched for personal data, and the file for what it carries.
3. Read the card: "Nothing to fix" or "Fix this", with a button per fix that opens the tool with the same file. The full report is there to keep.

Questions:
- Q: Does it change my file?
  A: No. It only reads the file and gives you a report and a CSV.
- Q: Does a clean report mean the file is safe?
  A: Not on its own. The check looks in the usual hiding places; still open the file and read it before sending.
- Q: Are my documents uploaded?
  A: No. The check runs in your browser; the file is not uploaded.

### Fit a mail's size limit

https://pdf.orihako.com/fit-mail/ (ja: https://pdf.orihako.com/ja/fit-mail/, fr: https://pdf.orihako.com/fr/fit-mail/)

Make a PDF small enough to send by email. It is first made smaller without changing any picture; if that is not enough, photos go to the standard quality; if it is still too big, it is cut between pages.

Also runs in the desktop agent. Callable from other sites through /embed/ as "fit-mail".

How to:
1. Drop one PDF.
2. Choose the limit of the mail it goes through. If you are not sure, keep 10 MB.
3. Press Run. Orihako says how far it went (as it was, smaller, or cut); send cut parts one per email.

Questions:
- Q: Why does it aim below the limit itself?
  A: Email carries an attachment as text, which makes it about 1.37 times bigger on the way. So for a 10 MB limit the file is made about 7.2 MB at most.
- Q: Will it look worse?
  A: Not at first: it is made smaller without changing any picture. Only when that is not enough are photos set to the standard quality, which still prints well. Text and lines never change.
- Q: How do I send the parts?
  A: They are named in order, like quote_1of3.pdf and quote_2of3.pdf. Attach one per email and put 1/3, 2/3 in the subject so the reader knows the order.

### PDF to Word

https://pdf.orihako.com/pdf-to-word/ (ja: https://pdf.orihako.com/ja/pdf-to-word/, fr: https://pdf.orihako.com/fr/pdf-to-word/)

The text of a PDF as an editable Word file (.docx), with headings, page breaks and ruled tables. Your files are never uploaded.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "pdf-to-word".

How to:
1. Drop one PDF. A scanned PDF has its words read first (the site asks before it downloads what it reads them with).
2. It starts as soon as the file is in: the text is read paragraph by paragraph.
3. Save the .docx and open it in Word or Google Docs.

Questions:
- Q: Do layout, tables and pictures carry over?
  A: The words do (paragraphs, headings, page breaks), and tables drawn with lines become Word tables. Two columns are read one after the other. Pictures are left out. Use it as a draft to edit.
- Q: What about a scanned PDF?
  A: Pages with no text have their words read from the page first. Some words may be misread, so check the document.
- Q: Is my file sent anywhere?
  A: No. Reading the text and writing the .docx both happen in your browser.

### PDF to text

https://pdf.orihako.com/pdf-to-text/ (ja: https://pdf.orihako.com/ja/pdf-to-text/, fr: https://pdf.orihako.com/fr/pdf-to-text/)

A PDF's text, in reading order, as one plain text file (.txt). Any app opens it, and Orihako Chat's library takes it.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "pdf-to-text".

How to:
1. Drop one PDF with text (for a scan, run Text recognition first: it reads the words on the pages).
2. It starts as soon as the file is in: the text is read page by page.
3. Save the .txt, or put it in Chat's library and ask about it.

Questions:
- Q: How is this different from PDF to Word?
  A: Plain words only, with no headings or page breaks. Made for search, AI and other apps. To edit while keeping the look, use PDF to Word.
- Q: What about a scanned PDF?
  A: It holds no text, so run it through Text recognition first (it reads the words on the pages), then convert.
- Q: Is my file sent anywhere?
  A: No. Reading happens in your browser and nowhere else.

### PDF to table

https://pdf.orihako.com/pdf-to-table/ (ja: https://pdf.orihako.com/ja/pdf-to-table/, fr: https://pdf.orihako.com/fr/pdf-to-table/)

The words of a PDF placed in rows and columns by where they sit, saved for Excel (.xlsx) and as a CSV. Check it against the page.

Caution: The table is an estimate made from where the words sit on the page: cells can be merged, split or shifted. Check it against the PDF before you rely on it.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "pdf-to-table".

How to:
1. Drop one PDF with text (run a scanned PDF through text recognition first).
2. Choose the pages with the table, or leave blank for every page, and press Run.
3. Save the .xlsx for Excel or the .csv, or open the table in Orihako Data to tidy it.

Questions:
- Q: How exact is the table?
  A: It is an estimate. A PDF keeps words at positions, not cells, so the columns come from where the words sit. Merged cells, text that wraps inside a cell and tables without clear gaps can land in the wrong place. Compare it with the PDF.
- Q: What about a scanned PDF?
  A: It holds no text, so there is nothing to place. Run it through Text recognition (OCR) first, then make the table.
- Q: Is my file uploaded?
  A: No. The table is made in your browser.

### Read a PDF aloud

https://pdf.orihako.com/read-aloud/ (ja: https://pdf.orihako.com/ja/read-aloud/, fr: https://pdf.orihako.com/fr/read-aloud/)

The PDF's text, read by your computer's own voice: check a contract by ear, listen to a paper on the move. The text is sent nowhere.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "read-aloud".

How to:
1. Drop one PDF with text.
2. It starts as soon as the file is in: the text is read.
3. Press Read aloud. The same button stops it. The text can also be saved as .txt.

Questions:
- Q: Can I choose the voice?
  A: The voices installed on your computer are used. Add more in your operating system's speech settings.
- Q: What about a scanned PDF?
  A: It holds no text, so run it through Text recognition first (it reads the words on the pages).
- Q: Is the text sent anywhere?
  A: No. Reading and speaking both happen on this computer.

### Summarize PDF

https://pdf.orihako.com/summarize/ (ja: https://pdf.orihako.com/ja/summarize/, fr: https://pdf.orihako.com/fr/summarize/)

The browser's built-in AI lists the key points of a PDF. Your files are never uploaded.

Browser only: the desktop agent sends the person to this page.

How to:
1. Drop one PDF with text (for a scan, run Text recognition first: it reads the words on the pages).
2. Press Run. The first time, the browser downloads its AI once.
3. The summary appears on the page, and can be saved as a Markdown file.

Questions:
- Q: Is my document sent anywhere?
  A: No. Chrome's built-in AI (Gemini Nano) writes the summary on your computer. The browser downloads the model once; after that it works offline.
- Q: Which browsers can do this?
  A: Recent desktop Chrome, on computers that meet its requirements (22 GB free space, and 16 GB of memory or a capable GPU). Other browsers do not have it yet.
- Q: Is the summary accurate?
  A: It is a draft written by an AI. Check numbers, names and who does what against the document before relying on it.

### Sign and send back

https://pdf.orihako.com/sign-return/ (ja: https://pdf.orihako.com/ja/sign-return/, fr: https://pdf.orihako.com/fr/sign-return/)

Put your signature or seal and the date on a PDF you received: it is fixed into the page, made smaller and named "<name>_signed.pdf", ready to attach to your reply.

Also runs in the desktop agent.

How to:
1. Drop the PDF you received.
2. Press "Place my saved signature", "Place my saved seal" or "Place today's date", then click where it goes on the page. The first time, make one with Signature or Seal in the toolbar.
3. Press Run: a fixed, smaller PDF named _signed comes back. Attach it to your reply.

Questions:
- Q: Where are my signature and seal kept?
  A: Only in this browser, when "Keep it on this device" is ticked; they are not uploaded. A seal is kept as its words and shape and shows the date of the day it is placed. "Forget" removes either at any time.
- Q: Is it a legal signature?
  A: It is a picture showing agreement, like a scanned signature or seal; it is not a digital signature with a certificate. Check what the other side accepts.
- Q: Does fixing and shrinking change how it looks?
  A: No. What you placed and any form fields are drawn into the page so they cannot be edited, and the file is made smaller without lowering picture quality. If it does not get smaller, it keeps its size.

### Fill and sign

https://pdf.orihako.com/fill-sign/ (ja: https://pdf.orihako.com/ja/fill-sign/, fr: https://pdf.orihako.com/fr/fill-sign/)

Type into a PDF form, then add text, the date, check marks, your signature or a seal anywhere.

Caution: Form fields are found automatically, but some PDFs build their forms in ways that cannot be filled here (XFA forms, fields drawn as plain lines). Open the downloaded file and check what you entered.

Also runs in the desktop agent.

How to:
1. Drop one PDF.
2. Type into the highlighted form fields, or pick a tool and click the page to place text, a date, a mark, your signature or a seal.
3. Choose whether to lock the entries, press Run and download.

Questions:
- Q: What is free?
  A: Everything: typing into form fields and placing text, marks, signatures, seals and pictures are free and unlimited.
- Q: Is a drawn signature legally binding?
  A: A drawn signature or seal image shows agreement the way a scanned one does; it is not a certificate-based digital signature. Check what the recipient accepts.
- Q: What does locking do?
  A: It fixes what you entered into the page so nobody can change it, and every app shows it the same way.

### Rotate PDF

https://pdf.orihako.com/rotate/ (ja: https://pdf.orihako.com/ja/rotate/, fr: https://pdf.orihako.com/fr/rotate/)

Turn some or all pages by 90, 180 or 270 degrees.

Also runs in the desktop agent. Callable from other sites through /embed/ as "rotate".

How to:
1. Drop one PDF file.
2. Choose the rotation and, if you want, the pages, for example 2,5-7. Blank means every page.
3. Press Run and download the rotated PDF.

Questions:
- Q: Is the rotation permanent?
  A: Yes. It is written into the file, so every viewer and printer shows the page the new way.
- Q: My scan was already rotated in the file. Will it turn twice?
  A: No. Orihako reads the rotation the file already has and adds yours to it.
- Q: Does it change image quality?
  A: No. Only the page's direction changes; images and text are untouched.

### Delete pages

https://pdf.orihako.com/delete-pages/ (ja: https://pdf.orihako.com/ja/delete-pages/, fr: https://pdf.orihako.com/fr/delete-pages/)

Remove the pages you do not need and keep the rest.

Also runs in the desktop agent. Callable from other sites through /embed/ as "delete-pages".

How to:
1. Drop one PDF file.
2. Click the pages to remove in the thumbnails, or type their numbers, for example 1,4-6.
3. Press Run and download the PDF without those pages.

Questions:
- Q: Can I delete the last page only?
  A: Yes. Click the last page in the thumbnails, or type its number.
- Q: Does the file get smaller?
  A: Usually. Anything used only by the removed pages is dropped when the file is saved.
- Q: What if I remove every page?
  A: Orihako refuses, because a PDF with no pages is not a valid document.

### Reorder pages

https://pdf.orihako.com/reorder/ (ja: https://pdf.orihako.com/ja/reorder/, fr: https://pdf.orihako.com/fr/reorder/)

Drag the pages into a new order, or type it, and save the result.

Also runs in the desktop agent. Callable from other sites through /embed/ as "reorder".

How to:
1. Drop one PDF file. Its pages appear as thumbnails.
2. Drag a page to where it belongs, or use the arrows on each page. The order box fills in for you.
3. Press Run and download the reordered PDF.

Questions:
- Q: Can I duplicate a page?
  A: Yes, by typing: an order like 1,1,2-4 makes two copies of page 1. Pages left out of a typed order are dropped.
- Q: Does it work on a phone?
  A: Yes. Where dragging is awkward, the small arrows on each page move it one step, and the order can always be typed.
- Q: Are bookmarks and links kept?
  A: Links inside a page are kept. The file's bookmarks are not carried over; you can add them again with Add bookmarks.

### Crop PDF

https://pdf.orihako.com/crop/ (ja: https://pdf.orihako.com/ja/crop/, fr: https://pdf.orihako.com/fr/crop/)

Trim white margins automatically, cut a fixed margin, or keep an area you draw.

Caution: Trimming white margins automatically decides where the content ends; faint lines, page numbers or specks can make it cut less, or more, than you expect. Check the result.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "crop".

How to:
1. Drop one PDF.
2. Choose automatic trim, a fixed margin, or draw a box on the preview.
3. Press Run and download the cropped PDF.

Questions:
- Q: Is the cut part deleted?
  A: Not by default: cropping narrows the visible area and the rest stays in the file, hidden. Choose Remove it from the file in the folded settings, or press Remove the outside after the run, and the text, pictures and shapes outside are taken out of the file (a picture across the edge is cut). The page looks the same.
- Q: How does automatic trim work?
  A: Orihako finds where the text and pictures are on each page and keeps the margin you set around them. Empty pages are left as they are.
- Q: Can I crop only some pages?
  A: Yes. Type a page selection such as 1-3,5. Blank means every page.

### Change page size

https://pdf.orihako.com/resize-pages/ (ja: https://pdf.orihako.com/ja/resize-pages/, fr: https://pdf.orihako.com/fr/resize-pages/)

Scale pages to A4, A3, Letter and other paper sizes, centred, without losing sharpness.

Also runs in the desktop agent. Callable from other sites through /embed/ as "resize-pages".

How to:
1. Drop one PDF.
2. Choose the paper size and, if you want, the pages.
3. Press Run and download the resized PDF.

Questions:
- Q: Does the text get blurry?
  A: No. Pages are scaled without turning them into pictures, so text and lines stay sharp.
- Q: What about landscape pages?
  A: Each page keeps its orientation: a landscape page lands on landscape paper of the size you chose.
- Q: Are links kept?
  A: Links and form fields sit at fixed positions and are removed from resized pages, since they would no longer line up.

### Pages per sheet

https://pdf.orihako.com/n-up/ (ja: https://pdf.orihako.com/ja/n-up/, fr: https://pdf.orihako.com/fr/n-up/)

Print 2, 4, 9 or 16 pages on one sheet, or fold a booklet.

Also runs in the desktop agent. Callable from other sites through /embed/ as "n-up".

How to:
1. Drop one PDF.
2. Choose how many pages per sheet (or booklet), the paper and the binding side.
3. Press Run and print the new PDF double-sided (booklet: flip on the short edge).

Questions:
- Q: How do I print the booklet?
  A: Print double-sided, flipping on the short edge, then fold the stack in half. Pages are padded with blanks to a multiple of four.
- Q: What is right binding?
  A: For books read right to left, such as vertical Japanese: page 1 goes on the right and pages run leftwards.
- Q: Are the pages shrunk?
  A: Yes, a little, to fit each cell; they are not turned into pictures, so text and lines stay sharp.

### Split spreads

https://pdf.orihako.com/halve-pages/ (ja: https://pdf.orihako.com/ja/halve-pages/, fr: https://pdf.orihako.com/fr/halve-pages/)

Cut scanned two-page spreads into single pages at the fold, in reading order.

Also runs in the desktop agent. Callable from other sites through /embed/ as "halve-pages".

How to:
1. Drop one PDF of scanned spreads.
2. Check the cut and the order in the preview. Press where a page should be cut to move the line.
3. Press Run and save the PDF with one page per half.

Questions:
- Q: Does it resample the scan?
  A: No. The scan is not redrawn: each half shows part of the same page, turned upright when needed, so the quality is the original's. Searchable text, links and bookmarks stay on the half they belong to.
- Q: My book reads right to left.
  A: With the binding on Automatic, a book written vertically has its right page first. If the order is wrong, choose Right or Left.
- Q: The cover is a single page.
  A: Pages shaped like a single page (a cover) stay whole on their own. You can also press Keep this page whole under the preview.

### Remove blank pages

https://pdf.orihako.com/remove-blank/ (ja: https://pdf.orihako.com/ja/remove-blank/, fr: https://pdf.orihako.com/fr/remove-blank/)

Find the empty pages a scanner left behind and delete them.

Caution: Blank pages are judged by how they look. A page with only faint text may be removed, and a blank page with specks may stay. Check the page numbers listed after the run.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "remove-blank".

How to:
1. Drop one scanned PDF.
2. Keep normal sensitivity, or choose strict (only perfectly clean pages) or loose (pages with a few specks).
3. Press Run; Orihako lists the pages it removed.

Questions:
- Q: How does it decide a page is blank?
  A: Each page is looked at in small size; if almost nothing on it is dark, it counts as blank. The edges, where scanners leave shadows, are ignored.
- Q: A page with a faint mark was removed.
  A: Choose strict sensitivity, which removes only pages with almost nothing on them, and run again on the original.
- Q: Is anything changed on the other pages?
  A: No. The kept pages are copied as they are.

### Lock form entries (flatten)

https://pdf.orihako.com/flatten/ (ja: https://pdf.orihako.com/ja/flatten/, fr: https://pdf.orihako.com/fr/flatten/)

Fix filled-in form fields and comments into the page, so nobody can change them.

Also runs in the desktop agent. Callable from other sites through /embed/ as "flatten".

How to:
1. Drop one PDF with form fields or comments.
2. Choose forms only, or forms and comments.
3. Press Run and download the locked PDF.

Questions:
- Q: Why lock the entries?
  A: Nobody can change the values afterwards, the file prints the same everywhere, and some offices only accept locked files.
- Q: Are links kept?
  A: Yes. Links and pop-up notes stay; hidden fields are removed.
- Q: A field came out empty.
  A: Some PDFs keep a value without drawing it. Fill the form with Fill and sign first, then lock it.

### Add bookmarks

https://pdf.orihako.com/bookmarks/ (ja: https://pdf.orihako.com/ja/bookmarks/, fr: https://pdf.orihako.com/fr/bookmarks/)

Write a PDF's table of contents: titles, pages and levels, in any language.

Also runs in the desktop agent. Callable from other sites through /embed/ as "bookmarks".

How to:
1. Drop one PDF.
2. Type one bookmark per line: the page number and the title, indented with two spaces for a sub-entry.
3. Choose add or replace, press Run and download.

Questions:
- Q: What does a line look like?
  A: "3 Introduction" or "Introduction ... 3". Two leading spaces, a tab or a dash make it a child of the line above.
- Q: Will existing bookmarks be kept?
  A: With add, new entries follow the existing ones; with replace, only yours remain.
- Q: Does merging keep bookmarks now?
  A: Yes. Merge keeps each file's bookmarks and can add one bookmark per file.

### Extract images

https://pdf.orihako.com/extract-images/ (ja: https://pdf.orihako.com/ja/extract-images/, fr: https://pdf.orihako.com/fr/extract-images/)

Save every picture in a PDF as its own image file, at full quality.

Also runs in the desktop agent. Callable from other sites through /embed/ as "extract-images".

How to:
1. Drop one PDF.
2. Choose which images to keep (to skip small icons).
3. Press Run and download the images, or all of them as a ZIP.

Questions:
- Q: Is the quality the same as in the PDF?
  A: Yes. JPG images come out exactly as they are; the others are saved as lossless PNG.
- Q: Why are some pictures missing?
  A: Small images are skipped by the setting, and drawings made of lines are not images. Use PDF to images to save whole pages.
- Q: I got a .jp2 file. What is it?
  A: A JPEG 2000 image, taken out as it was. Most image apps open it.

### Text recognition (OCR)

https://pdf.orihako.com/ocr/ (ja: https://pdf.orihako.com/ja/ocr/, fr: https://pdf.orihako.com/fr/ocr/)

Read the text of a scanned PDF so you can search and copy it. The text is also saved as a text file.

Caution: Recognition is not 100% accurate: handwriting, faint or skewed scans and very small text cause mistakes. Check the text before you rely on search or copy.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "ocr".

How to:
1. Drop the scanned PDF.
2. Choose the language(s) of the document and, if you want, the pages.
3. Press Run. Each page is read on this device; then download the searchable PDF and the text file.

Questions:
- Q: Is the scan sent to a server for recognition?
  A: No. The text recognition runs inside this page. The reading data is downloaded from this site the first time and kept on your device.
- Q: How accurate is it?
  A: Good on clean, straight scans of printed text. On our own Japanese test pages (invoices, estimates, contracts, two-column and vertical pages), about 1 to 2 characters in 100 were wrong in horizontal text and about 4 in 100 in vertical text. Tables drawn with lines are read cell by cell. Weaker on handwriting and on faded, fax-like scans.
- Q: Why is the first run slow?
  A: The first time, the reading data has to be downloaded (about 18 MB for Japanese, a few MB for English or French): the page shows its size and asks first. After that a page takes a few seconds to a little over ten, depending on the computer or device.

### AI Mask a PDF

https://pdf.orihako.com/mask-for-ai/ (ja: https://pdf.orihako.com/ja/mask-for-ai/, fr: https://pdf.orihako.com/fr/mask-for-ai/)

Makes a .txt of the PDF's text with company and people's names, amounts, phone numbers and more replaced by placeholders like 【Company A】 and 【Phone 1】. Ask ChatGPT or Claude with it; the answer gets the real names back on the AI Mask page.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "mask-for-ai".

How to:
1. Drop one PDF with text (for a scan, run Text recognition first: it reads the words on the pages).
2. It starts as soon as the file is in: names from your list, phones, emails, addresses and amounts become placeholders like 【Phone 1】.
3. Read the text, copy it and paste it into the AI. Paste the AI's answer on the AI Mask page and the placeholders become the real names again.

Questions:
- Q: What is masked?
  A: E-mail addresses, phone and card numbers, ID numbers, postal codes, addresses, birth dates and account numbers, found by their shape. Amounts can be masked, rounded (about $10,000) or kept. The same value always gets the same placeholder, so the text still reads.
- Q: Are names masked?
  A: Only the words in your AI Mask list (add them on orihako.com's AI Mask page; the list stays on this device). A name that is not in the list cannot be found: read the result before you paste it.
- Q: Is the file or the key sent anywhere?
  A: Masking and the key stay on this PC. What reaches the outside AI is only what you copy or attach. The key (which placeholder stands for which word) is kept in orihako.com's storage on this device for 30 days and can be deleted on the AI Mask page at any time.

### Scanner-storage check

https://pdf.orihako.com/scan-check/ (ja: https://pdf.orihako.com/ja/scan-check/, fr: https://pdf.orihako.com/fr/scan-check/)

For each page of a scanned PDF, reads the resolution (200 dpi or more) and the colour depth (colour, 256 levels) on your device and makes a report (CSV and a printable HTML) against Japan's scanner-storage rule. The file is not changed.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "scan-check".

How to:
1. Drop one scanned PDF.
2. It starts as soon as the file is in: each page's picture is measured for pixels and colours.
3. Open the HTML report, fill in who checked and when, and keep it with the file.

Questions:
- Q: What does it check?
  A: Each page's scanned picture: its resolution (pixels over the page size) and colour depth (colour, greyscale or black and white). 200 dpi or more and colour counts as meeting the rule.
- Q: Does it check timestamps or retention?
  A: No. It reads only the numbers inside the file. The operating rules are the tax office's guidance.
- Q: Is my file sent anywhere?
  A: No. The reading happens in your browser and nowhere else.

### Proofread (repeats, mixed spellings)

https://pdf.orihako.com/proofread/ (ja: https://pdf.orihako.com/ja/proofread/, fr: https://pdf.orihako.com/fr/proofread/)

Checks the PDF's text for repeated words, mixed punctuation and spellings, full-width letters, half-width kana, unclosed brackets and very long sentences, and lists them by page and line (HTML and CSV). The PDF is not changed.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "proofread".

How to:
1. Drop one PDF with text (for a scan, run Text recognition first: it reads the words on the pages).
2. It starts as soon as the file is in: each page's text is read and checked against the rules.
3. Open the list (HTML) and fix the original.

Questions:
- Q: What does it find?
  A: Repeated words ("the the"), mixed punctuation styles, two spellings of one word, full-width letters and digits, half-width kana, shortened potential forms in Japanese, unclosed brackets, very long sentences and extra spaces.
- Q: Does it check grammar or meaning?
  A: No: only mechanical slips a rule can see. Read the document through before sending it.
- Q: Is the file sent anywhere?
  A: No. Reading and checking happen in this computer's browser only.

### Compare two PDFs

https://pdf.orihako.com/compare/ (ja: https://pdf.orihako.com/ja/compare/, fr: https://pdf.orihako.com/fr/compare/)

See what changed between two versions: removed words in red, added words in green, side by side, saved as a PDF.

Caution: Differences can be missed, or marked where there are none. Comparing by text uses the text stored in the PDF, so choose appearance for scans. Files without text are compared page number by page number, so there a page added or removed puts the pages after it out of step.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "compare".

How to:
1. Drop the old version first, then the new one (use the arrows to swap them).
2. Choose to compare the text, or the appearance (for scans and drawings).
3. Press Run. Download the side-by-side PDF and the text file listing every change.

Questions:
- Q: What does the result look like?
  A: One landscape page per page pair: the old page on the left, the new one on the right, with a header counting the changes. Removed words are shaded red, added words green.
- Q: The pages moved; does it still work?
  A: Yes, when the pages have text: each page is set against the page most like it, so a page inserted shows as added, one taken out shows as removed, and the pages after it still meet their old selves. Scans without text are compared page number by page number.
- Q: Can it compare scans?
  A: Choose Appearance: the two pages are laid over each other and the areas that differ are marked. To compare word by word, run Text recognition (OCR) on both files first.

### Page numbers

https://pdf.orihako.com/page-numbers/ (ja: https://pdf.orihako.com/ja/page-numbers/, fr: https://pdf.orihako.com/fr/page-numbers/)

Add page numbers, a header or a footer, such as 3 / 12 or Confidential, to every page.

Also runs in the desktop agent. Callable from other sites through /embed/ as "page-numbers".

How to:
1. Drop one PDF file.
2. Write the format, for example {n} / {total}, choose the position and size, and optionally the pages.
3. Press Run and download the numbered PDF.

Questions:
- Q: What can the format contain?
  A: Any text. {n} becomes the page's number and {total} the count of numbered pages. A format without them is a plain header or footer.
- Q: Can numbering start at a number other than 1?
  A: Yes. Set the start number; the first selected page gets it and the rest follow.
- Q: Does it work on rotated or mixed-size pages?
  A: Yes. Positions follow each page as it is displayed, so a landscape page in a portrait file is numbered at its own bottom edge.

### Bates numbering

https://pdf.orihako.com/bates/ (ja: https://pdf.orihako.com/ja/bates/, fr: https://pdf.orihako.com/fr/bates/)

Stamp every page of one or many PDFs with a running number such as ABC000001, continuing from file to file, with a CSV log of each file's range.

Also runs in the desktop agent. Callable from other sites through /embed/ as "bates".

How to:
1. Drop your PDFs and put them in order with the arrows: numbering runs through them in that order.
2. Set the prefix (for example ABC), the first number and the number of digits; add a suffix if you need one.
3. Press Run, then download the numbered PDFs and bates-log.csv, which lists each file's first and last number.

Questions:
- Q: Does numbering continue across files?
  A: Yes. The first page of the second file gets the number after the last page of the first file.
- Q: What does the CSV log contain?
  A: One row per file: its name, first number, last number and page count, for your production records.
- Q: Are my documents uploaded?
  A: No. Numbering happens in your browser; the files are not uploaded.

### Exhibit labels

https://pdf.orihako.com/exhibits/ (ja: https://pdf.orihako.com/ja/exhibits/, fr: https://pdf.orihako.com/fr/exhibits/)

Label each PDF as Exhibit A, B, C (or Exhibit 1, Pièce n° 1, 甲第1号証) on its first page, name the files after their labels and get the list of exhibits as a PDF and a CSV.

Also runs in the desktop agent. Callable from other sites through /embed/ as "exhibits".

How to:
1. Drop your PDFs and put them in order with the arrows: labels follow that order.
2. Choose the label style, the first number and where the label goes.
3. Press Run, then download the labelled PDFs, exhibit-list.pdf and exhibit-list.csv.

Questions:
- Q: Can I use my own wording?
  A: Yes. Choose Custom and type it, with {n} for the number or {A} for a letter, for example Annex {n}.
- Q: Is the label on every page?
  A: On the first page by default. Choose Every page to put it on all of them.
- Q: Are my documents uploaded?
  A: No. Labelling happens in your browser; the files are not uploaded.

### Document bundle

https://pdf.orihako.com/bundle/ (ja: https://pdf.orihako.com/ja/bundle/, fr: https://pdf.orihako.com/fr/bundle/)

Put PDFs together behind an index that links to each document, with a bookmark per document, page numbers straight through and the file opening at 100%.

Also runs in the desktop agent. Callable from other sites through /embed/ as "bundle".

How to:
1. Drop your PDFs and put them in the order they should appear.
2. Give the bundle a title and, if you like, a title per document, one line each in the same order.
3. Press Run and download the bundle: the index on page 1 links to every document.

Questions:
- Q: What does the index show?
  A: Each document's number, its title and the pages it runs over in the bundle. Click a line to go to that document.
- Q: Do the documents keep their own bookmarks?
  A: Yes. Each document gets a bookmark, with its own bookmarks underneath.
- Q: Are my documents uploaded?
  A: No. The bundle is made in your browser; the files are not uploaded.

### Protect with password

https://pdf.orihako.com/protect/ (ja: https://pdf.orihako.com/ja/protect/, fr: https://pdf.orihako.com/fr/protect/)

Encrypt a PDF so it asks for a password when opened.

Caution: A password stops people who do not know it from opening the file. Anyone who knows it can copy, print or pass the content on, so share it carefully and choose a long password.

Also runs in the desktop agent. Callable from other sites through /embed/ as "protect".

How to:
1. Drop one PDF file.
2. Type the password readers will need. Optionally add a different owner password.
3. Press Run and download the protected PDF.

Questions:
- Q: Which apps can open the protected file?
  A: Adobe Acrobat, web browsers, phone apps and every common PDF app. It uses the standard, widely supported encryption. A password with accents or other scripts gets newer, stronger encryption, which PDF apps older than 2008 may not open.
- Q: What is the owner password for?
  A: It is an administrator password that can change permissions or remove the protection. If you leave it empty, the password to open is used for both.
- Q: Is the password sent anywhere?
  A: No. It is only used on this device to encrypt the file, and it is not stored.

### Remove password

https://pdf.orihako.com/unlock/ (ja: https://pdf.orihako.com/ja/unlock/, fr: https://pdf.orihako.com/fr/unlock/)

Take the password off a PDF you know the password of.

Also runs in the desktop agent. Callable from other sites through /embed/ as "unlock".

How to:
1. Drop the protected PDF file.
2. Type its password.
3. Press Run and download the PDF without a password.

Questions:
- Q: Can it crack a password I do not know?
  A: No. It only removes protection when given the correct password.
- Q: Which PDFs can it unlock?
  A: Nearly all protected PDFs you meet in practice; it supports the standard protection methods.
- Q: Do I need to remove a password before using other tools?
  A: No. Every tool asks for the password when you drop a protected PDF. Use this tool when you want a copy with the protection removed.

### Watermark

https://pdf.orihako.com/watermark/ (ja: https://pdf.orihako.com/ja/watermark/, fr: https://pdf.orihako.com/fr/watermark/)

Put text such as CONFIDENTIAL, or your own image, across the pages, translucent, at any angle. Place it by hand in the preview.

Also runs in the desktop agent. Callable from other sites through /embed/ as "watermark".

How to:
1. Drop one PDF file.
2. Type the text or choose an image, then drag it into place in the preview: the corner resizes it, the knob turns it.
3. Press Run and download the watermarked PDF.

Questions:
- Q: Will Japanese text show correctly on other computers?
  A: Yes. Orihako puts the shapes of the characters it uses inside the PDF, so the watermark looks the same everywhere.
- Q: Can the watermark be removed?
  A: By a PDF editor, yes: it is a text overlay, like any watermark tool produces. It deters and labels; it is not a security measure.
- Q: Can I watermark only some pages?
  A: Yes. Type a page selection such as 1,3-5. Blank means every page.

### Stamp

https://pdf.orihako.com/stamp/ (ja: https://pdf.orihako.com/ja/stamp/, fr: https://pdf.orihako.com/fr/stamp/)

Press a square or round seal with up to four lines of text, like a company seal or a date stamp.

Also runs in the desktop agent. Callable from other sites through /embed/ as "stamp".

How to:
1. Drop one PDF file.
2. Type up to four lines, choose the shape, corner, size and colour.
3. Press Run and download the stamped PDF.

Questions:
- Q: Is this a legally binding electronic seal?
  A: No. It is a visual mark, like an ink stamp on paper. For signatures with legal weight use a digital signature service.
- Q: Can I use my own seal image?
  A: This tool draws the stamp from text. If you have an image of your seal, place it with the Picture tool in Fill and sign, or with Watermark at 100% opacity.
- Q: Where does the stamp go?
  A: Any corner or the centre of the page, with a small margin, on the pages you select.

### Split a scanned bundle

https://pdf.orihako.com/split-bundle/ (ja: https://pdf.orihako.com/ja/split-bundle/, fr: https://pdf.orihako.com/fr/split-bundle/)

One scanned PDF holding many documents becomes one PDF per document. Where each starts is found (a blank sheet, the page number back to 1, a title such as Invoice or Receipt), shown on the pages for you to check, and each is named by kind, date and company in a ZIP with a folder per kind.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "split-bundle".

How to:
1. Drop the one PDF your scanner made.
2. The pages appear with a ✂ where each document seems to start and blank sheets faded. Press a ✂ between two pages to add or remove a cut; press a page to leave it out or take it back.
3. Press Run: one PDF per document, named like Invoice_20260930_Company, in a ZIP with a folder per kind.

Questions:
- Q: How does it find where a document starts?
  A: From what the pages show: a blank separator sheet, a page number that starts again at 1, a large title (Invoice, Receipt, Quote, Contract, Delivery note, Purchase order), or a page laid out unlike the one before. It can be wrong, so every cut is shown on the pages before anything is split.
- Q: My scanner's PDF has no text. Does it still work?
  A: Yes: the pages are read with text recognition (OCR) in your browser first, which takes a little while and asks before downloading the reading data once. Blank sheets are found without it.
- Q: Can it do this every day by itself?
  A: Free: one bundle at a time on this page. Running it on a watched folder (your scanner's save folder) is planned for Business; it is not available yet.

### Rename invoices

https://pdf.orihako.com/rename-invoices/ (ja: https://pdf.orihako.com/ja/rename-invoices/, fr: https://pdf.orihako.com/fr/rename-invoices/)

Name invoice PDFs by date, issuer and amount automatically, check the table, download with a CSV index.

Caution: Date, company and amount are guessed from the document's text and can be wrong. Check and correct the table before downloading; highlighted cells need a closer look.

Browser only: the desktop agent sends the person to this page. Callable from other sites through /embed/ as "rename-invoices".

How to:
1. Drop your invoice or receipt PDFs, as many as you like.
2. Keep the file name pattern (date_issuer_amount to start with) or change it, then press Run.
3. Check and correct the table, then download the renamed files and the CSV index as a ZIP.

Questions:
- Q: How does it find the date and amount?
  A: It reads the text of the first pages, looks for words such as invoice date, total and amount due, and picks the issuer's company name. Scanned invoices are read with text recognition (OCR) on your device.
- Q: What if a value is wrong?
  A: Every date, issuer and amount can be corrected in the table; the file names update as you type.
- Q: Are the PDFs changed?
  A: No. Only the names change; the contents of every file stay exactly as they were.

### E-invoice reader (Factur-X, ZUGFeRD)

https://pdf.orihako.com/e-invoice/ (ja: https://pdf.orihako.com/ja/e-invoice/, fr: https://pdf.orihako.com/fr/e-invoice/)

Read the invoice data attached inside Factur-X, ZUGFeRD and XRechnung PDFs: seller, number, dates and amounts into a CSV, the XML saved beside, files renamed from it.

Also runs in the desktop agent. Callable from other sites through /embed/ as "e-invoice".

How to:
1. Drop your e-invoice PDFs.
2. Choose whether to rename them, and the name pattern.
3. Press Run, then download e-invoices.csv, the XML files and the renamed PDFs.

Questions:
- Q: Which invoices can it read?
  A: PDFs with the invoice XML attached, as Factur-X, ZUGFeRD and XRechnung do, and PDFs carrying a UBL invoice. A PDF without it is listed as none.
- Q: Does it check that the invoice is valid?
  A: No. It reads what the XML says; it does not validate it against the standard.
- Q: Are my invoices uploaded?
  A: No. Everything happens in your browser; the files are not uploaded.

Also called: 請求書をメールで送る / Envoyer des factures par e-mail

Lock the form, remove author details and shrink to under 3 MB, ready to attach.

Before an invoice or a quote goes out by e-mail, its form fields should be fixed so nobody edits the amounts, the author and software details inside the file should go, and the file should fit the recipient's attachment limit. This recipe does the three, in order, for every file you drop.

2. Remove author info (remove-metadata)

Make scanned invoices searchable, then file them in year/month folders with the date in the name.

Invoices kept for tax records have to be found again, by date and by the words in them. This recipe reads the text of scanned invoices (PDFs that already have text are left as they are), keeps full quality, and names each result with the date in a year/month folder, ready for your archive.

Black out personal data, flatten, remove author details and protect with a password.

A contract leaving the office must not carry what the recipient should not see.

Also called: スキャンの束を整える / Nettoyer une pile de scans

Remove blank pages, recognise text where needed, compress.

A scanner fed a stack of mixed paper leaves blank backs and heavy files. This recipe removes blank pages, reads the text of pages that have none and compresses. Check the removed pages if your paper has very light printing.

1. Remove blank pages (remove-blank)
2. Text recognition (OCR) (only for scans) (ocr)
3. Compress PDF (compress)

#### Tidy up book spreads

Also called: 見開きスキャンを整える / Remettre en ordre des doubles pages

Cut each spread in two, trim the margins, fit every page to A4.

Scanning a book or a bound report gives two pages per image with uneven margins. This recipe cuts every spread down the middle, trims the empty margins and fits every page to A4, so the result reads and prints like the original.

1. Split spreads (halve-pages)
2. Crop PDF (crop)
3. Change page size (resize-pages)

#### Check scans before storing them as originals

https://pdf.orihako.com/recipes/jp-scan-preservation/ (ja: https://pdf.orihako.com/ja/recipes/jp-scan-preservation/, fr: https://pdf.orihako.com/fr/recipes/jp-scan-preservation/)
Also called: スキャナ保存の前に要件をチェック / Vérifier des scans avant archivage (Japon)

Make scans searchable, pack them without loss, then check resolution and the other requirements.

Japan's electronic bookkeeping act lets scans replace paper when they meet requirements (resolution, colour). This recipe makes unreadable scans searchable, repacks them without loss and ends with a checklist report. One file at a time.

1. Text recognition (OCR) (only for scans) (ocr)
2. Compress PDF (compress)
3. Scanner-storage check (scan-check)

#### How to redact a PDF without Adobe, and check the text is really gone

https://pdf.orihako.com/guide/redact-pdf-without-adobe/

Before a contract, a court exhibit or a record with personal details goes out, some of it must go. This guide shows how to black it out for good, in your browser, without uploading the file anywhere.

Why a black box is not enough:
A black rectangle, a highlight or a comment drawn over text in a PDF only covers it. The text is still in the file: anyone who receives it can select it, search for it, copy it or move the box away. Court filings and public releases have exposed confidential details exactly this way.
Text blacked out in Word before exporting to PDF can survive in the same way, depending on how it was done.

How Orihako blacks out a page:
Every page that has a box is replaced by a picture of itself with the boxes already painted in. No text is left on that page to select, search or copy. Pages without a box keep their text.
The whole job runs inside your browser. The file is never sent to us or to anyone else.

Steps:
1. Open Black out (redact) and drop your PDF. Its pages appear at reading size.
2. Type the names or numbers to remove in "Words to black out, one per line". Every occurrence on every page gets a box.
3. Drag boxes over anything the search cannot find, such as signatures, handwriting or pictures. Click a box to remove it.
4. Choose the quality of the blacked-out pages: Standard for screens, High for printing.
5. Press Run and download the result.

Check that it worked:
- Open the downloaded file and search for each word you removed (Ctrl+F or Cmd+F). There should be no match.
- Try to select text on a blacked-out page. Nothing should highlight.
- Words that were not found are listed after the run. They were not blacked out: draw boxes over them and run again.

Things to know:
- Scanned pages have no text, so the word search cannot find anything on them. Draw boxes instead.
- Blacked-out pages become pictures, so their remaining text cannot be searched. Run Text recognition (OCR) on the result if the filing needs to be searchable.
- Names can also hide in the file's properties. Run Remove author info too, and give the file a neutral name.

Questions:
- Q: Can someone recover the blacked-out text from the file?
  A: Not from the file Orihako makes: a blacked-out page is a picture with the box painted in, and the original text is not in it. Your original file is not changed, so keep it safe separately.
- Q: Is my PDF uploaded?
  A: No. Opening, searching, blacking out and saving all happen in your browser.
- Q: Is this a Pro feature?
  A: No. It is free for one file at a time. Running it on many files at once, or chaining it with other tools in a recipe, needs Pro.

#### Make a scanned PDF searchable, without uploading it

https://pdf.orihako.com/guide/make-scanned-pdf-searchable/

Scanned contracts, statements and records are hard to work with until you can search them. Here is how to add text to a scan without sending it to an online service.

Why a scan cannot be searched:
A scanner or a phone camera saves each page as a picture. It looks like text to you, but the file holds no letters, so search, copy and screen readers find nothing.

What text recognition does:
It reads the letters in the picture and lays them over the page as invisible text. The page looks exactly as before, and your PDF app can now search it and copy from it. You also get the text as a plain text file.
Recognition runs on your device. The scan is never uploaded.

Steps:
1. Open Text recognition (OCR) and drop the scanned PDF.
2. Choose the language of the document: English, French, Japanese, or Japanese and English.
3. To read only some pages, type them in Pages, for example 1-3,5.
4. Press Run. The first run takes longer while the reading data loads; later runs take a few seconds per page.
5. Download the searchable PDF and the text file, then search the PDF to check.

Tips for good results:
- Scan pages straight, well lit, with the quality setting turned up.
- Turn sideways or upside-down pages first with Rotate PDF.
- Handwriting, faint print and very small text cause mistakes. Recognition is never 100% accurate, so check names and numbers that matter.
- One run reads up to 200 pages. For the rest, choose the next pages and run again.

Questions:
- Q: Is my scan uploaded?
  A: No. The recognition engine runs inside this page. Its reading data is downloaded from this site once and then kept on your device.
- Q: Which languages are supported?
  A: English, French and Japanese.
- Q: Is this a Pro feature?
  A: No. It is free for one file at a time. Running it on many files at once, or chaining it with other tools in a recipe, needs Pro.

#### Compress a PDF to fit an email or upload size limit

https://pdf.orihako.com/guide/compress-pdf-size-limit/

"Attachment too large" or "file exceeds the maximum size" usually means photos or scans. Here is how to get under the limit without uploading the file to a compression website.

Why PDFs get big:
Almost always because of pictures. Phone cameras and scanners make images far sharper than a screen needs, so a few pages can reach tens of MB. A PDF with only text is usually small.
Email services cap attachments (Gmail at 25 MB in total), and many work systems and filing portals set lower limits.

The three levels:
- Balanced (recommended): brings large photos down to a quality that still prints well. Text and lines stay as they are.
- Lossless (no quality change): removes waste inside the file without touching image quality. Saves less.
- Strong (smallest, Pro): lowers photo quality further for the smallest file. Best for email and on-screen reading.

Steps:
1. Open Compress PDF and drop one PDF.
2. Keep Balanced (recommended) and press Run.
3. The sizes before and after are shown. Check that the file is under your limit.
4. Still too big? Try Strong, or type the size it must fit under.
5. Open the downloaded file to check it looks right before you send it.

If it still does not fit:
- Text-only and already-compressed PDFs barely shrink. Orihako never returns a bigger file: if it cannot help, you get the original back.
- Delete pages you do not need with Delete pages.
- Split the file with Split PDF and send the parts separately.
- One file can be up to 500 MB.

Questions:
- Q: Is it free?
  A: Every level is free for one file at a time. Compressing many files at once, or as part of a recipe, needs Pro.
- Q: Will the text get blurry?
  A: No. Only photos and scanned images are changed; text and lines stay sharp. Choose Lossless if you want no change at all.
- Q: Is my PDF uploaded?
  A: No. Compression happens in your browser.

#### Remove hidden author information from a PDF before you send it

https://pdf.orihako.com/guide/remove-pdf-metadata/

A PDF exported from Word or another app often records the name on that computer's account, the program and when it was edited. Here is how to clear it, free and without uploading the file.

What a PDF can reveal:
- Title, author, subject and keywords, often filled in automatically from the original document or the computer's account.
- The program that made the file, and when it was created and last changed.
- The names of people who left comments on it.

Steps:
1. Open Remove author info and drop one PDF.
2. Press Run. There is nothing to set.
3. Download the cleaned PDF.
4. Open it and look at the document properties in your PDF app: author and title are empty.

What it does not remove:
- Names or details written on the pages themselves. Use Black out (redact) for those.
- Information inside pictures, such as a letterhead or a signature.
- What was typed into form fields.
- The file name. Rename the file before sending it.

Questions:
- Q: Does it change how the pages look?
  A: No. Pages, links, form fields and comments stay; only the hidden information and comment author names are removed.
- Q: Is it free?
  A: Yes, with no limit on use.
- Q: Is my PDF uploaded?
  A: No. It is cleaned in your browser.

#### Rename invoice PDFs by date, vendor and amount, with a CSV index

https://pdf.orihako.com/guide/rename-invoice-pdfs/

Invoices and receipts arrive with names that say nothing. Renaming them by date, vendor and amount makes them easy to find at tax time and easy to hand to your accountant.

What it does:
Drop many invoice or receipt PDFs at once. Orihako reads each one for the date, the issuer's company name and the total, and names the file from them. You check the results in a table; editing a cell renames the file straight away. A CSV index that opens in Excel comes with the files.
Only the names change; the contents of every PDF stay exactly as they were. Your files are never uploaded.

Steps:
1. Open Rename invoices and drop your invoice PDFs.
2. Keep the file name pattern, date_issuer_amount, or change it. {date}, {party}, {amount} and {original} are replaced.
3. If some invoices are scans, choose "Read them with text recognition (OCR, slower)" under Scanned invoices.
4. Press Run. Check the table: highlighted cells were guessed or not found, so look at those first.
5. Download the renamed files and the CSV together as a ZIP.

How values are read:
- Dates such as September 13, 2026, 13 Sep 2026, 2026-09-13 and 09/13/2026 are read; on the English site, numeric dates are read month first. A date like 03/04/2026, which could be read either way, is highlighted.
- The total is taken next to words such as Total, Amount due or Balance due. Cents are left out of the file name.
- Reading is never 100% accurate, especially on unusual layouts. Always check the table.
- One run takes up to 200 files and 500 MB.

Questions:
- Q: Are my invoices uploaded?
  A: No. Reading and renaming happen in your browser.
- Q: Is this tax or bookkeeping advice?
  A: No. It names files consistently. Ask your accountant how your records should be kept.
- Q: Is this a Pro feature?
  A: No. It is free for one file at a time. Running it on many files at once, or chaining it with other tools in a recipe, needs Pro.

#### Merge PDFs without uploading them: tax papers, contracts and records

https://pdf.orihako.com/guide/merge-pdfs-without-uploading/

Combining bank statements for a loan, tax forms for an accountant or records for a claim means handling documents you would rather not upload. Here is how to merge them on your own device, for free.

Why it matters where the merging happens:
Most online PDF services upload your files, process them on their servers and delete them later. With Orihako, the files are read and merged inside your browser and never sent to us or anyone else.
If you work under rules about where client or patient documents may go, check your organisation's policy. Orihako does not receive your files, but only your policy can say what is allowed.

Steps:
1. Open Merge PDF and drop two or more PDFs, or click the box to choose them.
2. Put them in order with the arrows. Click a page thumbnail to leave that page out.
3. Under Bookmarks, keep each file's bookmarks, or also add one bookmark per file.
4. Press Run and download the merged PDF.

Good to know:
- Password-protected PDFs work: a password box appears when you drop one.
- One run takes up to 200 files and 500 MB in total; on a phone, about 200 MB is a sensible ceiling.
- After merging, Compress PDF can bring the file under an email or portal limit.

Questions:
- Q: Is it free?
  A: Yes, with no limit on how often you use it.
- Q: Does it work offline?
  A: Yes. Once the page has loaded, merging keeps working without an internet connection.
- Q: Are my files uploaded?
  A: No. They are merged in your browser.

#### How to Bates number PDFs without Adobe Acrobat Pro

https://pdf.orihako.com/guide/bates-number-pdfs/

Bates numbering gives every page of a document production a unique, sequential number so it can be cited and tracked. Acrobat's Bates tool comes with its Pro plan; here is how to do it in your browser instead.

What a Bates number looks like:
A prefix, often a case or party code, followed by a zero-padded number: ABC000001, ABC000002 and so on. Numbering runs through the whole set, so the first page of the second document follows the last page of the first.

Steps:
1. Open Bates numbering and drop your PDFs.
2. Put them in production order with the arrows.
3. Set the prefix, the first number and the number of digits. To continue an earlier production, start after its last number. Add a suffix if your protocol uses one.
4. Choose the position; bottom right is common. The preview shows the first page's number.
5. Press Run and download the numbered PDFs together with bates-log.csv.

Before you produce:
- Check your agreed protocol or local rules for the prefix, the digits and where the number goes.
- Numbers are drawn on the page, like printed text.
- Keep the CSV log with your production records: one row per file with its first and last number.
- If you also need to redact, black out first and number afterwards, so no number is covered.

Questions:
- Q: Can I continue from an earlier production?
  A: Yes. Set the first number to the one after your last Bates number.
- Q: Are my documents uploaded?
  A: No. Numbering happens in your browser; the files are not uploaded.
- Q: Is this a Pro feature?
  A: No. It is free for one set of files at a time. Numbering many sets in one go, or as part of a recipe, needs Pro.

#### Prepare a PDF for court e-filing or an upload portal

https://pdf.orihako.com/guide/prepare-pdf-for-court-efiling/

Court e-filing systems and government portals set their own rules for uploads, typically a maximum file size and documents that can no longer be edited. Always check your court's or portal's current requirements; this guide shows how to meet the common ones without sending your documents to a conversion website.

What portals commonly ask for:
- A maximum size per file, often tens of megabytes. A larger filing must be split into parts.
- No fillable fields or comments that can still change: flatten them.
- Text that can be searched and selected. Scanned pages need text recognition first.
- No hidden author information you did not mean to file.
- Requirements differ from one court or portal to another and change over time. Their own rules always win.

The quick route: the court filing recipe:
On the Workflow page, the ready-made court filing recipe runs Lock form entries (flatten), Remove author info, Compress PDF and Split PDF by file size (35 MB per part) in one go, on every file you drop. Change the size in the Split PDF step to match your portal before running.

Step by step:
1. If the document is a scan, run Text recognition (OCR) first so its text can be searched.
2. Open Workflow and choose the court filing recipe, or run the tools one after another.
3. In Split PDF, choose "By file size" and set the largest part to your portal's limit.
4. Run, then download the parts: brief-part-1.pdf, brief-part-2.pdf and so on.
5. Open each part and check the pages before you file.

Things to know:
- A single page larger than the limit becomes a part on its own. Compress it harder or scan it again.
- Flattening removes the ability to fill in fields, so keep your editable original.
- Redact before you file: use Black out (redact), then run the steps above.

Questions:
- Q: Does Orihako check that my filing meets the court's rules?
  A: No. It prepares the file; the court's or portal's own requirements decide. Check them before you file.
- Q: Is anything uploaded?
  A: No. Every step runs in your browser.
- Q: Is it free?
  A: Each step is free for one file at a time, text recognition and blacking out included. Running the steps in one go as a recipe, or on many files, needs Pro.

#### How to shrink PDFs for visa and immigration uploads (IRCC, USCIS, UK, Australia)

https://pdf.orihako.com/guide/compress-pdf-for-visa-upload/

Passports, bank statements and certificates have to fit a portal's size limit, and they are exactly the files you should not upload to a random website. This guide shows how to shrink them on your own device.

Upload limits we checked on 15 September 2026:
- IRCC (Canada): up to 4 MB per file in the secure account, and as low as 2 MB on some portals.
- USCIS online filing (US): up to 12 MB per file.
- IRS Document Upload Tool (US): 15 MB, 120 pages and 40 files per upload.
- UK visa document upload (UKVCAS): reported as 6 MB per file.
- ImmiAccount (Australia): 5 MB per attachment, and no password-protected PDFs.
- Portals change their limits. Always check the current instructions on the portal itself.

Steps:
1. Photos of documents? Open Images to PDF first and put the pages in order.
2. Open Compress PDF and drop the file.
3. In "Fit a portal's limit", pick your portal. The target size is set 10% under its limit.
4. Press Run. The sizes before and after are shown.
5. Open the result at 100% and check that every line is readable before you upload.

If the file is still too big:
- Scan in greyscale or black and white at 150-200 dpi: colour scans are the usual reason a page is heavy.
- Remove blank pages with Remove blank pages.
- Split one large document into parts with Split PDF, choosing "By file size" and the same portal.
- Upload one document per file where the portal allows it, instead of one huge PDF.

Doing a whole application at once:
The official recipes "Documents for an IRCC upload", "Evidence for USCIS online filing", "UK visa document upload" and "Attachments for ImmiAccount" chain these steps. Running a recipe on many files at once needs Pro.

Questions:
- Q: Are my passport scans uploaded?
  A: No. Compression runs in your browser; the files are never uploaded.
- Q: Does Orihako guarantee my application is accepted?
  A: No. It prepares the file; the immigration authority decides what it accepts. Check its instructions and that the result is readable.
- Q: Is it free?
  A: Yes, one file at a time. Many files at once, or chained steps, need Pro.

#### Compress a PDF to 100 KB, 200 KB, 500 KB or 1 MB

https://pdf.orihako.com/guide/compress-pdf-to-a-size/

"File must be under 200 KB" is a common rule on application forms. This guide shows how to hit a size exactly, and what to do when a scan will not go that small.

How the size target works:
Compress PDF has a "Fit under" field in megabytes: 0.1 for 100 KB, 0.2 for 200 KB, 0.5 for 500 KB, 1 for 1 MB. Orihako starts with your chosen level and tries stronger settings until the file is under the target.
If even the strongest setting cannot reach it, the page says so and gives you the smallest result.

Steps:
1. Open Compress PDF and drop the file.
2. Type the size in "Fit under", slightly below the limit (0.18 for a 200 KB limit).
3. Press Run, then open the result at 100% to check the text.

When it will not go small enough:
- Small sizes suit text documents. A full-colour photo page rarely fits in 100 KB and stays readable.
- Scan again in black and white, or crop the margins first.
- Split the document and upload the parts separately if the form allows it.

Questions:
- Q: Is the file uploaded?
  A: No. Everything runs in your browser.
- Q: Will the text stay sharp?
  A: Text drawn as text stays sharp. Scanned pages are pictures, so they soften as the size goes down. Always check the result.
- Q: Is it free?
  A: Yes, one file at a time.

PDFのコメント機能や図形で黒い四角を重ねた場合、見た目は隠れていても、下にある文字のデータはそのまま残っています。受け取った人が文字をコピーしたり、検索したり、四角を動かしたりすると、隠したはずの内容が読めてしまいます。
WordやExcelで文字を黒く塗ってからPDFにした場合も、塗り方によっては文字のデータが残ります。

Orihako の黒塗りのしくみ:
Orihako では、黒塗りしたページを、黒い四角ごと1枚の画像に置き換えます。下の文字のデータは残らないので、コピーや検索をしても出てきません。黒塗りのないページは、文字のまま残ります。
ファイルはお使いの端末の中で処理し、サーバーに上げません。社外に出せない書類でも使えます。

手順:
1. 「黒塗り（マスキング）」を開き、PDFをドロップします。ページが読める大きさで並びます。
2. 消したい名前や番号を「黒塗りする語」に1行に1つずつ入力します。全ページの該当する場所に四角が出ます。
3. 印影や手書きなど、文字として見つからない部分は、ページの上をドラッグして四角を描きます。四角をクリックすると消せます。
4. 「実行」を押して、黒塗りしたPDFをダウンロードします。
5. できあがったPDFを開き、消し漏れがないか、消した語で検索しても出てこないかを確かめます。

注意点:
- スキャンしたPDFには文字のデータがないため、語句の検索では見つかりません。四角を描いて指定してください。
- 見つからなかった語は、実行後の画面に表示されます。その語は黒塗りされていないので、四角を描いて指定してください。
- 黒塗りしたページは画像になるため、そのページの文字は選択や検索ができなくなります。検索できるようにしたいときは、あとから「文字認識（OCR）」をかけます。
- ファイル名や、ファイルに記録された作成者名に名前が残っていることがあります。「作成者情報の削除」も使い、ファイル名は保存するときに変えてください。

Questions:
- Q: 黒塗りしたPDFから、元の文字を取り出されることはありますか？
  A: 黒塗りしたページは画像に置き換えるので、Orihako で作ったファイルから、塗りつぶした部分の文字を取り出すことはできません。元のファイルは変更されないので、必要なら別に保管してください。
- Q: ファイルはサーバーに送られますか？
  A: 送られません。読み込み、語句の検索、黒塗り、保存まで、すべてお使いのブラウザの中で行います。
- Q: スキャンした書類でも使えますか？
  A: 使えます。語句の検索は効かないので、ページの上に四角を描いて指定してください。

#### 請求書PDFのファイル名を「日付_取引先_金額」にそろえる方法

https://pdf.orihako.com/ja/guide/invoice-file-names/

取引先からPDFで届く請求書や領収書は、ファイル名がばらばらで、あとから探すのが大変です。読み取った日付・取引先・金額で、まとめて名前をそろえる方法を説明します。

なぜファイル名をそろえるのか:
メールやダウンロードで受け取った請求書などのデータは、電子帳簿保存法により、電子のまま保存し、「取引の日付」「取引金額」「取引先」で探せるようにしておくことが求められています。
専用のシステムを使わない方法として、国税庁の案内では、ファイル名に日付・取引先・金額を決まった形で入れて保存する方法が紹介されています。
保存のルールはほかにもあり、事業の規模などによっては検索の条件が不要になる場合もあります。自社に必要なことは、国税庁の案内や税理士に確認してください。

Orihako でできること:
複数の請求書PDFをまとめて入れると、書類の文字から日付・発行元・金額を読み取り、ファイル名を付けます。結果は表で確認・修正でき、表を直すとファイル名もすぐ変わります。一覧のCSV（Excelで開けます）も一緒に作ります。
ファイルの中身は変わらず、名前だけが変わります。書類はサーバーに上げません。

手順:
1. 「請求書リネーム」を開き、請求書や領収書のPDFをまとめてドロップします。
2. 「ファイル名の形式」は、最初は「日付_発行元_金額」の形になっています。変えたいときだけ書き換えます。
3. 紙をスキャンしたPDFが含まれるときは、「スキャンした請求書」で「文字認識（OCR）で読む」を選びます（時間がかかります）。
4. 「実行」を押すと、読み取った結果が表に出ます。色の付いた欄は、推測した値か読み取れなかった欄なので、特に確認して直します。
5. 名前を変えたファイルとCSVの一覧を、ZIPでまとめてダウンロードして保存します。

注意点:
- 読み取りは100%正確ではありません。表の内容は必ず確認してください。
- 日付は「請求日」「発行日」などの言葉の近くを探しますが、支払期限などの別の日付を拾うことがあります。
- 金額は「ご請求金額」「合計」などの言葉の近くを探します。見つからないときは、いちばん大きい金額を仮に入れて、色を付けて知らせます。
- 1回に扱えるのは200ファイル・合計500MBまでです。

Questions:
- Q: この方法だけで電子帳簿保存法に対応できますか？
  A: ファイル名をそろえるのは、探せるようにするための方法の一つです。保存のルールはほかにもあるため、国税庁の案内や税理士にご確認ください。
- Q: 請求書の内容はどこかに送られますか？
  A: 送られません。読み取りも名前の変更も、お使いのブラウザの中で行います。
- Q: 領収書や見積書にも使えますか？
  A: 使えます。日付・会社名・金額が書かれた書類なら、同じように読み取ります。読み取れなかった欄は表で入力してください。

#### PDFに角印・日付印を押す方法（印影の画像がなくても作れます）

https://pdf.orihako.com/ja/guide/stamp-pdf/

PDFを印刷して印を押し、スキャンし直すと時間がかかり、画質も落ちます。PDFのまま印を重ねれば、数十秒で済みます。

角印・日付印ツールの手順:
1. 「角印・日付印」を開き、PDFを1つドロップします。ページのプレビューが表示されます。
2. 「印影の文字」に1行ずつ入力します（最大4行）。例：1行目に「承認」、2行目に「2026.09.14」。会社の角印なら、会社名を2〜4行に分けて入れます。
3. 形（四角・丸）、文字の向き（横書き・縦書き）、色、大きさを選びます。
4. プレビューの印をドラッグして、押したい場所に動かします。押すページは「ページ」で指定できます。
5. 「実行」を押して、印を押したPDFをダウンロードします。

印影の画像を持っている場合:
- 背景が透明な印影の画像（PNG）があれば、「入力・署名」の「画像」で、ページの好きな場所に置けます。
- 「透かし」で文字を空欄にして画像を選び、濃さを100%にしても押せます。複数のページの同じ位置に押すときに便利です。

注意点:
- ここで作る印は、紙に押す印と同じ「見た目の印」です。法的な効力のある電子署名が必要な場合は、電子署名サービスを使ってください。
- 他人や他社の印を無断で作ったり押したりしないでください。
- 印を押したPDFは、お使いの端末の中で作ります。書類はサーバーに上げません。

Questions:
- Q: 縦書きの印は作れますか？
  A: 作れます。「文字の向き」で「縦書き」を選んでください。
- Q: 日付を毎回入れ直す必要がありますか？
  A: 印影の文字は実行のたびに入力します。Pro では、よく使う設定を保存して呼び出せます。
- Q: 押した印はあとから動かせますか？
  A: 印はページの一部として書き込むので、あとから動かすことはできません。元のファイルは変わらないので、やり直すときは元のファイルからもう一度押してください。

#### スキャンしたPDFを、文字で検索・コピーできるようにする方法

https://pdf.orihako.com/ja/guide/searchable-pdf-ocr/

スキャンした契約書や資料から、必要な言葉を探したい、文章をコピーしたい、というときの方法です。

スキャンしたPDFが検索できない理由:
スキャナーやスマートフォンで作ったPDFは、ページ全体が1枚の写真のようなものです。人の目には文字に見えても、PDFの中に文字のデータがないため、検索やコピーができません。

文字認識（OCR）でできること:
写真の中の文字を読み取り、見えない文字のデータとしてページに重ねます。見た目は元のスキャンのままで、PDFを開くアプリで検索したり、文字を選んでコピーしたりできるようになります。読み取った文章は、テキストファイルとしても保存できます。
読み取りはお使いの端末の中で行い、書類はサーバーに上げません。

手順:
1. 「文字認識（OCR）」を開き、スキャンしたPDFをドロップします。
2. 「文書の言語」を選びます。日本語の書類なら「日本語と英語」のままで大丈夫です。
3. 一部のページだけ読みたいときは、「ページ」に「1-3,5」のように入力します。
4. 「実行」を押します。初回だけ、読み取り用のデータを読み込むため少し時間がかかります。
5. できあがったPDFとテキストファイルをダウンロードし、PDFを開いて検索できるか確かめます。

うまく読み取るコツ:
- スキャンするときは、ページをまっすぐ置き、明るく、画質の設定を高めにします。
- 横向きや逆さまのページは、先に「PDF回転」で向きを直します。
- 手書き、かすれた文字、とても小さい文字は誤りやすくなります。
- 読み取りは100%正確ではありません。大事な数字や名前は、読み取った文字を目で確認してください。
- 1回に読み取れるのは200ページまでです。続きは、ページを指定してもう一度実行します。

Questions:
- Q: 書類はサーバーに送られますか？
  A: 送られません。文字を読み取る仕組みも、このページの中で動きます。初回だけ読み取り用のデータをこのサイトから読み込み、以後は端末に保存されます。
- Q: 1ページにどれくらい時間がかかりますか？
  A: 端末にもよりますが、2回目からは1ページ数秒ほどです。
- Q: 黒塗りしたPDFも検索できるようになりますか？
  A: 黒塗りしたページは画像になるので、文字認識をかけると、黒塗りしていない部分の文字が検索できるようになります。「まとめて処理」で「黒塗り」と「文字認識（OCR）」をつなげると一度で済みます。

#### PDFを小さくしてメールに添付する方法

https://pdf.orihako.com/ja/guide/compress-pdf-email/

メールで送ろうとしたら「容量が大きすぎます」と出た、というときの方法です。多くの場合、写真やスキャンした画像を整えるだけで、ずっと小さくなります。

PDFが大きくなる理由:
ほとんどの場合、原因は写真やスキャンした画像です。スマートフォンのカメラやスキャナーは、画面で見るには必要以上にきめ細かい画像を作るため、数ページでも数十MBになることがあります。文字だけのPDFは、もともと小さいのが普通です。
メールには添付できる容量の上限があり、たとえば Gmail は合計25MBまでです。会社のメールでは、もっと小さい上限のこともあります。

3つの圧縮のしかた:
- 標準（おすすめ）：大きな写真だけを、印刷してもきれいな画質に整えます。文字や線はそのままです。
- 無劣化：画質を一切変えずに、ファイルの中の無駄だけを減らします。小さくなる量は少なめです。
- 強力：写真の画質をさらに下げて、いちばん小さくします。メールで送る、画面で見る、という用途に向いています。

手順:
1. 「PDF圧縮」を開き、PDFを1つドロップします。
2. まずは「標準（おすすめ）」のまま「実行」を押します。
3. 圧縮前と後の容量が表示されるので、メールの上限などに収まったか確かめます。
4. まだ大きいときは「強力」を選ぶか、「目標サイズ（MB・空欄でもOK）」に上限より少し小さい値を入れて、もう一度実行します。
5. ダウンロードしたPDFを開き、見た目に問題がないか確かめてから送ります。

それでも小さくならないとき:
- 文字だけのPDFや、すでに圧縮されたPDFはあまり小さくなりません。元より大きくなることはなく、小さくできなければ元のままお返しします。
- 不要なページを「ページ削除」で消すと、そのぶん小さくなります。
- 「PDF分割」で分けて、何通かのメールに分けて送る方法もあります。
- 1回に扱えるのは1ファイル500MBまでです。

Questions:
- Q: 無料で使えますか？
  A: 無料です。1つのファイルなら、どの圧縮のしかたも回数の制限なく使えます。いくつものファイルを一度に圧縮するのは Pro の機能です。
- Q: 画質は悪くなりますか？
  A: 「標準」は大きな写真だけを、印刷しても十分きれいな画質に整えます。文字や線はそのままです。画質を一切変えたくないときは「無劣化」を選んでください。
- Q: ファイルはサーバーに送られますか？
  A: 送られません。圧縮はお使いのブラウザの中で行います。

#### 確定申告・年末調整の書類を1つのPDFにまとめる方法

https://pdf.orihako.com/ja/guide/merge-pdf-tax-documents/

確定申告や年末調整の時期は、書類がPDF、スマホの写真、スキャンとばらばらに集まります。提出先や税理士に渡す前に、1つのファイルに整える方法を説明します。

結合する前にそろえておくもの:
- スマホで撮った控除証明書などの写真は、先に「画像 → PDF」でPDFにしておきます。
- ネットで発行された証明書など、パスワード付きのPDFもそのまま使えます。入れると入力欄が出るので、パスワードを入れてください。
- 提出する順番を決めておきます。受け取る人が見る順（収入の書類、控除の書類、領収書など）にすると親切です。

手順:
1. 「PDF結合」を開き、まとめたいPDFを2つ以上ドロップします。枠をクリックして選ぶこともできます。
2. 矢印ボタンで、提出する順番に並べます。
3. 白紙や控えのページなど、いらないページはサムネイルをクリックして外します。
4. 「しおり」で「ファイルごとのしおりも追加する」を選ぶと、開いた人が書類ごとに移動できて、探しやすくなります。
5. 「実行」を押して、できあがったPDFをダウンロードします。開いて、順番と抜けがないかを確かめます。

提出先の容量に収める:
e-Tax で添付書類をPDF（イメージデータ）で送るときは、1回の送信の容量に上限があります。2026年9月時点の案内では、1回の送信あたり14.0 MBまでです。会社の年末調整のシステムにも、1ファイル3 MB前後などの上限があることがよくあります。上限は変わることがあるので、提出前に必ず提出先の案内を確認してください。
大きすぎるときは「PDF圧縮」で小さくします。それでも収まらなければ、「PDF分割」の「容量で分ける（1ファイルを指定の大きさ以下に）」で、上限より小さいファイルに分けて送ります。
レシピ「e-Tax の添付書類（イメージデータ）を送る」は、結合・圧縮・分割を一度に行います。控除証明書の写真をまとめるなら、レシピ「年末調整の控除証明書をまとめる」もあります。レシピを一度に実行するのは Pro の機能です。

注意点:
- 1回に扱えるのは200ファイル・合計500MBまでです。スマートフォンでは、合計200MB程度までが目安です。
- 結合しても、書類の中身や画質は変わりません。
- どの書類を添付するか、原本の提出や保管が必要かは、書類によって違います。国税庁の案内や、勤め先・税理士に確認してください。

Questions:
- Q: 無料で使えますか？
  A: 無料です。回数の制限もありません。
- Q: 書類はサーバーに送られますか？
  A: 送られません。読み込みから結合まで、お使いのブラウザの中で行います。源泉徴収票のように個人情報の多い書類でも、外に送らずにまとめられます。
- Q: スマートフォンでもできますか？
  A: できます。ファイルが大きいと時間がかかったり、途中で止まったりすることがあるので、合計200MB程度までにしてください。

#### PDFの不要なページを削除する方法（順番の入れ替えも）

https://pdf.orihako.com/ja/guide/delete-pdf-pages/

スキャンで紛れた白紙、社外に出さない添付、差し替える前の表紙など、PDFの一部のページだけを消したいときの方法です。元のファイルは変わらないので、安心してやり直せます。

手順:
1. 「ページ削除」を開き、PDFを1つドロップします。ページがサムネイルで並びます。
2. 消したいページのサムネイルをクリックして選びます。番号がわかっているときは、「ページ」に「1,4-6」のように入力しても選べます。
3. 選んだページを確かめて「実行」を押し、削除後のPDFをダウンロードします。
4. ダウンロードしたPDFを開き、残したいページまで消えていないか確かめます。

目的に合ったツールを選ぶ:
- 白紙のページがたくさんある：「白紙ページ削除」なら、白紙を自動で見つけてまとめて消せます。少し汚れたページも白紙として扱うかは「感度」で選べます。
- 順番を入れ替えたい：「ページ並べ替え」で、サムネイルをドラッグして好きな位置に動かします。
- 一部のページだけを別のファイルにしたい：「PDF分割」の「ページで分ける」を使います。
- 横向きや逆さまのページがある：消さずに「PDF回転」で向きを直せます。

注意点:
- ページを消すと、多くの場合ファイルも小さくなります。消したページだけが使っていた画像などのデータは、保存するときに取り除かれます。
- すべてのページを選ぶと、ページのないPDFは作れないため、実行せずにお知らせします。
- パスワード付きのPDFも、入れるとパスワードの入力欄が出るので、そのまま使えます。
- ページを消しても、残したページに書かれた名前や番号はそのままです。見せたくない部分だけを隠したいときは「黒塗り（マスキング）」を使います。

Questions:
- Q: 最後のページだけ削除できますか？
  A: できます。サムネイルで最後のページをクリックしてください。
- Q: 消したページは元に戻せますか？
  A: 元のファイルは変更されないので、元のファイルからもう一度やり直せます。
- Q: 無料ですか？ファイルは送信されますか？
  A: 無料で、回数の制限もありません。ファイルはお使いのブラウザの中で処理し、サーバーに上げません。

#### PDFにパスワードをかけて送る方法と、パスワードの外し方

https://pdf.orihako.com/ja/guide/pdf-password/

社外に送る書類に「念のためパスワードを」と言われたときの方法です。ファイルもパスワードも、お使いの端末の外には出ません。

パスワードをかける手順:
1. 「パスワード保護」を開き、PDFを1つドロップします。
2. 「開くためのパスワード」を入力します。32文字までで、日本語も使えます。半角の英数字と記号だけなら、古いPDFアプリでも開けます。
3. 「所有者パスワード（任意）」は、あとで保護を外したり権限を変えたりするための管理用です。空欄なら、開くためのパスワードと同じになります。
4. 「実行」を押して、保護されたPDFをダウンロードします。
5. ダウンロードしたPDFを開き、パスワードを聞かれることを確かめてから送ります。

パスワードの伝え方:
PDFを送ったすぐあとに、パスワードを続けてメールで送る方法（いわゆるPPAP）は、メールを見られると両方とも見られてしまうため、やめる会社が増えています。パスワードは、電話やチャットなど、メールとは別の方法で伝えてください。
相手の会社の決まりで、パスワード付きのファイルを受け取れないこともあります。送る前に、受け取り方を確認しておくと安心です。
契約書を社外に出すときは、レシピ「契約書を社外に出す」で、個人情報の黒塗り・作成者情報の削除・パスワードを一度に済ませられます。レシピを一度に実行するのは Pro の機能です。

受け取ったPDFのパスワードを外す:
わからないパスワードを調べたり、破ったりすることはできません。正しいパスワードがわかっているPDFだけが対象です。
1. 「パスワード解除」を開き、保護されたPDFをドロップします。
2. そのPDFのパスワードを入力して「実行」を押します。
3. パスワードのないPDFをダウンロードします。

注意点:
- パスワードを知っている人は、中身をコピー・印刷・転送できます。送る相手に注意してください。
- 誕生日や社名など、推測されやすいものは避け、長めのパスワードにしてください。
- パスワードを忘れると開けなくなります。元のファイルは変わらないので、保護する前のファイルは手元に残しておきましょう。
- 提出先によっては、パスワード付きのPDFを受け付けないことがあります。提出先の案内を確認してください。

Questions:
- Q: 日本語のパスワードは使えますか？
  A: 使えます。日本語を含むパスワードは、より強い暗号化の方式で守ります。いまのAcrobat・ブラウザ・スマホのアプリでは開けますが、2008年より前のPDFアプリでは開けないことがあります。全角の英数字・半角カナ・全角スペースは、打つアプリによって別の文字になることがあるため使えません。
- Q: どのアプリで開けますか？
  A: Adobe Acrobat、ブラウザ、スマートフォンのアプリなど、一般的なPDFアプリで開けます。
- Q: パスワードはどこかに送られますか？
  A: 送られません。この端末の中でファイルを保護するのに使うだけで、保存もしません。

#### PDFをWordに変換して、文章を編集する方法

https://pdf.orihako.com/ja/guide/pdf-to-word/

受け取ったPDFの文章を直したい、以前の契約書をひな形に使いたい、というときの方法です。書類はサーバーに上げずに、ブラウザの中で変換します。

変換で残るもの・残らないもの:
見た目をそのまま再現する変換ではありませんが、文章を打ち直さずに済みます。編集のたたき台として使ってください。
- 残るもの：文章、段落、見出し、改ページ。
- 形が変わるもの：表。枠はなくなり、行ごとの文章になります。
- 残らないもの：画像、図、ページの細かいレイアウト。

手順:
1. 「PDF → Word」を開き、PDFを1つドロップします。
2. 「実行」を押します。ページの文章が段落ごとに読み取られます。
3. できた .docx をダウンロードし、Word や Google ドキュメントで開きます。
4. 見出しになった行や段落の区切りを確かめ、必要なところを直します。

スキャンしたPDFの場合:
紙をスキャンしたPDFには文字のデータがないため、そのままでは文章を取り出せません。先に「文字認識（OCR）」で文字を読み取ってから、「PDF → Word」にかけてください。
読み取りは100%正確ではありません。変換したあと、数字や名前は元の書類と見比べて確認してください。

ほかの方法:
- 文章だけをコピーして使いたいなら、「PDF → テキスト」でテキストファイルにする方法もあります。
- 書類の見た目はそのままで、空いたところに文字を書き足したいだけなら、「入力・署名」が向いています。

Questions:
- Q: ファイルはどこかに送られますか？
  A: 送られません。読み取りも .docx の作成も、お使いのブラウザの中で行います。社外に出せない書類でも、端末の外に出さずに変換できます。
- Q: 表をWordの表のまま変換できますか？
  A: できません。表は行ごとの文章になります。表の形が必要なときは、Wordで表に直してください。
- Q: 無料ですか？
  A: 無料で、回数の制限もありません。

#### PDFにページ番号を入れる方法（会議資料・提出書類に）

https://pdf.orihako.com/ja/guide/add-page-numbers/

「資料の何ページ目ですか」と聞かれないように、ページに番号を入れておくと便利です。印刷しても、画面で見ても、同じ位置に番号が出ます。

手順:
1. 「ページ番号」を開き、PDFを1つドロップします。
2. 「文字」に書式を入れます。最初は「{n} / {total}」で、{n} がそのページの番号、{total} がページ数に置き換わります。「{n}」だけ、「{n}ページ」「- {n} -」なども使えます。
3. 「位置」（下・中央など）と「文字の大きさ（pt）」を選びます。プレビューで見え方を確かめられます。
4. 「実行」を押して、番号入りのPDFをダウンロードします。

表紙に番号を入れない:
「ページ」に「2-」と入力すると、2ページ目から番号が入ります。このとき「開始番号」を1にすると、2ページ目が「1」になります。
「開始番号」は、前の資料の続きから番号を振るときにも使えます。

複数のファイルに通し番号を振る:
先に「PDF結合」で1つのファイルにまとめてから、ページ番号を入れます。
レシピ「会議資料を配布用にする」は、結合・用紙サイズの統一・ページ番号・「社外秘」の透かし・圧縮を一度に行います。レシピを一度に実行するのは Pro の機能です。
ファイルを分けたまま、ファイルをまたいで通し番号を振りたいときは「ベイツ番号（通し番号）」が使えます。

注意点:
- 番号は、印刷した文字と同じようにページに書き込まれます。あとから消したり動かしたりはできないので、元のファイルは残しておいてください。
- 「文字」に {n} を入れなければ、「社外秘」などのヘッダー・フッターの文字として使えます。
- 横向きのページが混ざっていても、そのページの見た目の下端に入ります。

Questions:
- Q: 「{n}ページ」のような形にできますか？
  A: できます。「文字」に「{n}ページ」と書けば、「1ページ」「2ページ」のように入ります。
- Q: ファイルは送信されますか？
  A: 送信されません。番号入れはお使いのブラウザの中で行います。
- Q: 無料ですか？
  A: 無料です。1つのファイルなら回数の制限もありません。いくつものファイルに一度に番号を入れるのは Pro の機能です。

#### Compresser un PDF à 300 Ko pour Études en France (Campus France)

https://pdf.orihako.com/fr/guide/compresser-pdf-300-ko-campus-france/

Relevés de notes, diplômes, passeport : chaque pièce doit tenir en 300 Ko. Ce guide montre comment y arriver sans envoyer vos documents à un site en ligne.

La limite à respecter:
Au 15 septembre 2026, la plateforme Études en France accepte des documents de 300 Ko au plus. Les limites changent : vérifiez toujours les consignes de votre espace Campus France avant l'envoi.
300 Ko, c'est peu pour une page scannée en couleur. Visez environ 270 Ko pour garder une marge.

Étapes:
1. Ouvrez Compresser un PDF et déposez votre document. Pour des photos, passez d'abord par Images en PDF.
2. Dans « Adapter à la limite d'un portail », choisissez Campus France (Études en France) : la taille visée passe à 0,27 Mo.
3. Choisissez le niveau Fort si le document reste trop lourd.
4. Lancez, puis ouvrez le résultat à 100 % pour vérifier que le texte se lit.
5. Téléchargez le fichier et donnez-lui un nom sans accents avant l'envoi.

Si le fichier dépasse encore 300 Ko:
- Scannez en noir et blanc ou en niveaux de gris, en qualité standard plutôt que maximale : c'est souvent la façon la plus efficace de gagner de la place.
- Recadrez les grandes marges blanches avant de compresser.
- Retirez les pages blanches ou inutiles avec Supprimer les pages blanches.
- Si plusieurs pages ne tiennent pas ensemble, envoyez-les séparément lorsque la plateforme le permet.

Questions:
- Q: Mes documents sont-ils envoyés quelque part ?
  A: Non. La compression se fait dans votre navigateur ; le fichier ne quitte pas votre appareil.
- Q: Orihako garantit-il que mon dossier sera accepté ?
  A: Non. Il prépare le fichier ; seule la plateforme décide. Vérifiez ses consignes et la lisibilité du résultat.
- Q: Est-ce gratuit ?
  A: Oui, un fichier à la fois. Traiter plusieurs fichiers d'un coup ou enchaîner les étapes demande Pro.

#### Anonymiser un PDF : masquer noms, NIR et IBAN pour de bon

https://pdf.orihako.com/fr/guide/anonymiser-un-pdf/

Avant de transmettre un dossier, une pièce ou une réponse à une demande d'accès, certaines données doivent disparaître. Ce guide montre comment les caviarder vraiment, sans envoyer le fichier.

Pourquoi un rectangle noir ne suffit pas:
Un rectangle ou un surlignage posé sur un texte ne fait que le couvrir : le texte reste dans le fichier et peut être sélectionné, copié ou retrouvé par une recherche.
Orihako remplace chaque page caviardée par une image où les zones sont déjà noircies. Il ne reste aucun texte à copier sur ces pages.

Étapes:
1. Ouvrez Caviarder (noircir) et déposez le PDF.
2. Tapez les noms ou mots à masquer dans « Mots à noircir, un par ligne ».
3. Dans « Trouver aussi par type », cochez le numéro de sécurité sociale (NIR), l'IBAN, l'e-mail ou le téléphone. Un numéro dont la clé de contrôle ne correspond pas n'est pas pris pour un NIR ou un IBAN.
4. Tracez des zones supplémentaires sur les signatures ou les éléments non trouvés.
5. Lancez, puis téléchargez le résultat et le rapport de vérification.

Vérifier avant d'envoyer:
- Relisez chaque page caviardée : une recherche automatique peut manquer un mot mal reconnu sur un scan.
- Retirez aussi les métadonnées (auteur, logiciel) avec Retirer les infos d'auteur.
- Gardez l'original non caviardé à part, dans un endroit sûr.

Questions:
- Q: Le fichier est-il envoyé en ligne ?
  A: Non. Le caviardage se fait dans votre navigateur.
- Q: Est-ce conforme au RGPD ?
  A: Orihako est un outil : la conformité dépend de ce que vous masquez et de votre démarche. Une relecture humaine reste nécessaire.
- Q: Est-ce gratuit ?
  A: Oui, un fichier à la fois. Caviarder plusieurs fichiers d'un coup ou l'enchaîner avec d'autres étapes demande Pro.

#### Fusionner des PDF sans les mettre en ligne : dossier de location, impôts, CAF

https://pdf.orihako.com/fr/guide/fusionner-pdf-sans-envoi/

Un dossier de location, une démarche auprès de la CAF ou un envoi à votre comptable demandent souvent un seul PDF. Ce guide montre comment l'assembler sur votre appareil, gratuitement.

Pourquoi fusionner sur votre appareil:
La plupart des sites de fusion en ligne téléversent vos fichiers sur leurs serveurs et les suppriment plus tard. Avec Orihako, les fichiers sont lus et assemblés dans votre navigateur : ils ne sont envoyés ni à nous, ni à personne.
C'est précieux pour les documents qu'on préfère garder pour soi : pièce d'identité, avis d'imposition, bulletins de salaire, relevés bancaires.

Étapes:
1. Ouvrez Fusionner des PDF et déposez deux fichiers ou plus, ou cliquez sur la zone pour les choisir. Pour des photos, passez d'abord par Images en PDF.
2. Mettez les fichiers dans l'ordre avec les flèches. Cliquez sur la miniature d'une page pour la laisser de côté.
3. Dans Signets, choisissez « Ajouter aussi un signet par fichier » : le destinataire passera d'un document à l'autre en un clic.
4. Appuyez sur Lancer et téléchargez le PDF fusionné. Ouvrez-le pour vérifier l'ordre et qu'il ne manque rien.

Pour un dossier de location:
La recette « Dossier de location filigrané » fusionne les pièces, écrit sur chaque page « DOSSIER DE LOCATION - USAGE EXCLUSIF », retire les infos d'auteur et compresse sous 5 Mo. La mention rend plus difficile la réutilisation de vos pièces à d'autres fins. Lancer une recette en une fois demande Pro.
La loi fixe la liste des pièces qu'un bailleur peut demander : ne fournissez que celles-ci. Le site service-public.fr la détaille.

Bon à savoir:
- Les PDF protégés par mot de passe fonctionnent : une case pour le mot de passe apparaît quand vous en déposez un.
- Jusqu'à 200 fichiers et 500 Mo au total par traitement ; sur un téléphone, visez environ 200 Mo.
- Si le fichier fusionné est trop lourd pour un e-mail ou un portail, passez-le ensuite dans Compresser un PDF.

Questions:
- Q: Est-ce gratuit ?
  A: Oui, sans limite d'utilisation.
- Q: Mes fichiers sont-ils envoyés en ligne ?
  A: Non. La fusion se fait dans votre navigateur ; une fois la page chargée, elle fonctionne même sans connexion.
- Q: Puis-je changer l'ordre des pages à l'intérieur d'un fichier ?
  A: Pas dans la fusion, qui garde l'ordre de chaque fichier. Utilisez Réorganiser les pages sur le résultat.

#### Réduire la taille d'un PDF pour l'envoyer par e-mail

https://pdf.orihako.com/fr/guide/reduire-taille-pdf-email/

« Pièce jointe trop volumineuse » : le message arrive souvent au pire moment. Dans la plupart des cas, il suffit d'alléger les photos et les scans du PDF, sans changement visible.

Pourquoi un PDF est lourd:
Presque toujours à cause des photos et des pages scannées. Un téléphone ou un scanner produit des images bien plus détaillées que ce qu'un écran affiche : quelques pages peuvent peser des dizaines de Mo. Un PDF qui ne contient que du texte est léger.
Les messageries limitent la taille des pièces jointes : 25 Mo chez Gmail, et souvent 10 Mo ou moins dans les messageries d'entreprise.

Les trois niveaux:
- Équilibrée (recommandée) : n'allège que les grandes photos, à une qualité qui s'imprime encore bien. Le texte et les traits restent intacts.
- Sans perte (qualité inchangée) : retire seulement ce qui est inutile dans le fichier. Le gain est plus faible.
- Forte (la plus légère) : baisse davantage la qualité des photos. Idéale pour l'e-mail et la lecture à l'écran.

Étapes:
1. Ouvrez Compresser un PDF et déposez le fichier.
2. Gardez Équilibrée (recommandée) et appuyez sur Lancer : Orihako affiche la taille avant et après.
3. Si c'est encore trop lourd, choisissez Forte, ou indiquez une « Taille visée (Mo, facultatif) » un peu sous la limite, par exemple 9 pour 10 Mo. Dans « Adapter à la limite d'un portail », le choix « Pièce jointe e-mail (limite courante de 10 Mo) » la remplit pour vous.
4. Ouvrez le résultat à 100 % pour vérifier que le texte se lit, puis joignez-le à votre e-mail.

Si le fichier ne diminue pas assez:
- Un PDF de texte ou déjà compressé diminue peu. Orihako ne rend jamais un fichier plus gros : sans gain, vous récupérez l'original.
- Retirez les pages inutiles avec Supprimer des pages, ou les pages vides d'un scan avec Supprimer les pages blanches.
- Découpez le document avec Diviser un PDF, « Par taille (chaque partie sous une limite) », et envoyez les parties dans plusieurs e-mails.
- Pour l'ANEF ou Campus France, voyez les guides dédiés : leurs limites sont plus strictes.

Questions:
- Q: Est-ce gratuit ?
  A: Oui, un fichier à la fois, quel que soit le niveau. Compresser plusieurs fichiers d'un coup demande Pro.
- Q: Mon PDF sera-t-il moins beau ?
  A: L'équilibrée garde une qualité qui s'imprime bien et ne touche pas au texte. Pour ne rien changer du tout, choisissez Sans perte.
- Q: Le fichier est-il envoyé en ligne ?
  A: Non. La compression se fait dans votre navigateur ; le fichier ne quitte pas votre appareil.

#### Signer un PDF sans l'imprimer : signature manuscrite, date et « Lu et approuvé »

https://pdf.orihako.com/fr/guide/signer-un-pdf/

Imprimer, signer, scanner : c'est long, et la copie est souvent de mauvaise qualité. Ce guide montre comment signer le PDF directement, dans votre navigateur.

Étapes:
1. Ouvrez Remplir et signer et déposez le PDF.
2. Si le document a des champs de formulaire, ils sont surlignés en bleu : cliquez dedans et tapez.
3. Choisissez Signature, dessinez-la à la souris, au doigt ou au stylet, appuyez sur Utiliser, puis cliquez à l'endroit où elle doit apparaître. Avec Sélection, vous pouvez la déplacer et la redimensionner.
4. Ajoutez la date du jour avec Date, et une mention comme « Lu et approuvé » ou « Bon pour accord » avec Texte.
5. Dans « Après le remplissage », choisissez « Figer (modification impossible ensuite) » pour que personne ne puisse changer ce que vous avez saisi.
6. Lancez, téléchargez, puis ouvrez le fichier pour vérifier chaque page signée.

Ce que vaut cette signature:
Une signature dessinée a la valeur d'une signature scannée : elle montre votre accord, et elle convient quand le destinataire accepte un document signé puis scanné.
Ce n'est pas une signature électronique « avancée » ou « qualifiée » au sens du règlement européen eIDAS, qui passe par un prestataire chargé de vérifier votre identité. Si un organisme ou un contrat l'exige, utilisez le service qu'il indique. En cas de doute, demandez au destinataire ce qu'il accepte.

Cas particuliers:
- Parapher chaque page : dessinez vos initiales avec Signature et placez-les sur chaque page avant de figer.
- Tampon d'entreprise : utilisez Tampon, ou Image pour placer l'image scannée de votre cachet.
- Document scanné sans champs : placez Texte, Coche ou Croix directement sur les cases.
- Certains formulaires sont construits d'une façon qui empêche de les remplir ici : vérifiez toujours le fichier téléchargé.
- Pour envoyer le formulaire signé à un organisme, la recette « Envoyer un formulaire rempli » fige les valeurs, retire les infos d'auteur et compresse sous 2 Mo. Lancer une recette en une fois demande Pro.

Questions:
- Q: Est-ce gratuit ?
  A: Oui. Remplir les champs et placer texte, coches, signatures, tampons et images est gratuit et illimité.
- Q: Ma signature est-elle enregistrée quelque part ?
  A: Non. Elle est dessinée et placée dans votre navigateur ; ni le document ni la signature ne sont envoyés, et Orihako ne la conserve pas.
- Q: Puis-je signer sur mon téléphone ?
  A: Oui. Dessinez la signature au doigt dans le cadre, puis touchez l'endroit où la placer.

#### Protéger un PDF par mot de passe avant de l'envoyer

https://pdf.orihako.com/fr/guide/proteger-pdf-mot-de-passe/

Un PDF protégé ne s'ouvre qu'avec son mot de passe. Ce guide montre comment en ajouter un dans votre navigateur : ni le fichier ni le mot de passe ne quittent votre appareil.

Étapes:
1. Ouvrez Protéger par mot de passe et déposez un PDF.
2. Saisissez le « Mot de passe d'ouverture » : lettres sans accent, chiffres et symboles, 32 caractères au plus.
3. Le « Mot de passe propriétaire (facultatif) » sert à modifier les permissions ou à retirer la protection plus tard. Laissé vide, le mot de passe d'ouverture sert aux deux.
4. Appuyez sur Lancer et téléchargez le PDF protégé.
5. Ouvrez-le pour vérifier que le mot de passe est bien demandé.

Transmettre le mot de passe:
N'envoyez pas le mot de passe dans le même e-mail que le fichier, ni dans un second e-mail juste après : quelqu'un qui lit l'un lit l'autre. Donnez-le par SMS, par téléphone ou de vive voix.
Pourquoi pas d'accents ? Les applications PDF ne traitent pas toutes les lettres accentuées de la même façon : un mot de passe avec « é » pourrait s'ouvrir ici et nulle part ailleurs.

Retirer un mot de passe:
L'outil ne devine pas un mot de passe inconnu : il faut connaître le bon.
1. Ouvrez Retirer le mot de passe et déposez le PDF protégé.
2. Saisissez son mot de passe, lancez, puis téléchargez la copie sans protection.

Bon à savoir:
- Toute personne qui connaît le mot de passe peut copier, imprimer ou transférer le contenu.
- Certains portails refusent les PDF protégés : vérifiez leurs consignes avant l'envoi.
- Gardez une copie non protégée en lieu sûr : sans le mot de passe, le fichier ne s'ouvre plus.
- Avant d'envoyer un contrat, la recette « Envoyer un contrat à l'extérieur » caviarde les données personnelles, fige le contenu, retire l'auteur et ajoute le mot de passe en une fois. Lancer une recette en une fois demande Pro.

Questions:
- Q: Quelles applications ouvrent le fichier protégé ?
  A: Adobe Acrobat, les navigateurs, les applications mobiles et toutes les applications PDF courantes.
- Q: Le mot de passe est-il envoyé quelque part ?
  A: Non. Il sert seulement à protéger le fichier sur cet appareil et n'est pas conservé.
- Q: Est-ce gratuit ?
  A: Oui, un fichier à la fois. Protéger plusieurs fichiers d'un coup demande Pro.

#### Rendre un PDF scanné cherchable (OCR), sans l'envoyer en ligne

https://pdf.orihako.com/fr/guide/pdf-scanne-cherchable-ocr/

Contrats, factures, courriers numérisés : tant qu'on ne peut pas y chercher, il faut tout relire. Voici comment ajouter le texte à vos scans dans votre navigateur.

Pourquoi on ne peut pas chercher dans un scan:
Un scanner ou un téléphone produit une photo de la page. À l'œil, c'est du texte ; pour l'ordinateur, ce n'est qu'une image. Il n'y a rien à chercher ni à copier.
La reconnaissance de texte (OCR) lit ces images et place le texte, invisible, sous chaque page. Le document garde exactement son aspect, mais la recherche et la copie fonctionnent. Le texte reconnu est aussi enregistré dans un fichier texte.

Étapes:
1. Ouvrez Reconnaissance de texte (OCR) et déposez le PDF scanné.
2. Dans « Langue du document », choisissez Français, ou Anglais pour un document en anglais.
3. Pour ne lire qu'une partie, indiquez les pages, par exemple 1-3,5.
4. Appuyez sur Lancer. La première fois, les données de lecture (quelques Mo) se chargent ; ensuite, une page prend quelques secondes.
5. Téléchargez le PDF cherchable et le fichier texte, puis essayez une recherche dans le PDF (Ctrl+F ou Cmd+F).

Pour un meilleur résultat:
- Scannez la page bien droite, bien éclairée, en bonne qualité.
- Redressez les pages couchées ou à l'envers avec Pivoter un PDF avant la reconnaissance.
- L'écriture manuscrite, les scans pâles et le très petit texte donnent plus d'erreurs.
- La reconnaissance n'est jamais exacte à 100 % : vérifiez les montants, les noms et les dates avant de vous y fier.
- Jusqu'à 200 pages par traitement ; pour la suite, choisissez les pages suivantes et relancez.
- Pour de nombreux scans, la recette « Rendre les scans consultables » ne lit que les fichiers sans texte, puis les compresse. Lancer une recette en une fois demande Pro.

Questions:
- Q: Le scan est-il envoyé à un serveur ?
  A: Non. La reconnaissance fonctionne dans cette page. Les données de lecture sont téléchargées depuis ce site la première fois, puis gardées sur votre appareil.
- Q: Puis-je ensuite obtenir un fichier Word ?
  A: Oui : passez le PDF cherchable dans PDF vers Word. Le texte, les titres et les sauts de page sont repris ; la mise en page et les images ne le sont pas.
- Q: Est-ce gratuit ?
  A: Oui, un fichier à la fois. Traiter plusieurs fichiers d'un coup demande Pro.

#### Supprimer les métadonnées d'un PDF avant de l'envoyer (auteur, logiciel, dates)

https://pdf.orihako.com/fr/guide/supprimer-metadonnees-pdf/

Nom du compte de l'ordinateur, nom de l'entreprise, date de création : un PDF en dit parfois plus que prévu. Ce guide montre comment le nettoyer gratuitement, sans téléverser le fichier.

Ce qu'un PDF peut révéler:
- Le titre, l'auteur, le sujet et les mots-clés, souvent remplis automatiquement à partir du document d'origine ou du compte de l'ordinateur.
- Le logiciel qui a créé le fichier, et les dates de création et de dernière modification.
- Le nom des personnes qui ont laissé des commentaires.

Étapes:
1. Ouvrez Retirer les infos d'auteur et déposez un PDF.
2. Appuyez sur Lancer. Il n'y a rien à régler.
3. Téléchargez le PDF nettoyé.
4. Ouvrez-le et regardez les propriétés du document dans votre lecteur PDF : l'auteur et le titre sont vides.

Ce que l'outil ne retire pas:
- Les noms et informations écrits sur les pages : pour ceux-là, utilisez Caviarder (noircir).
- Ce qui figure dans les images, comme un en-tête ou une signature.
- Ce qui a été saisi dans les champs de formulaire.
- Le nom du fichier : renommez-le avant l'envoi.

RGPD et données personnelles:
Retirer les métadonnées réduit ce que vous transmettez sans le vouloir, dans l'esprit du principe de minimisation des données du RGPD. Ce n'est qu'une étape : ce qu'il faut retirer dépend de votre situation.
Pour diffuser un document sans données personnelles, la recette « Anonymiser pour diffusion » caviarde e-mails, téléphones et numéros, retire les infos d'auteur et vérifie qu'il ne reste rien d'évident. Lancer une recette en une fois demande Pro.

Questions:
- Q: L'aspect des pages change-t-il ?
  A: Non. Les pages, les liens, les champs de formulaire et les commentaires restent ; seules les informations cachées et le nom des auteurs des commentaires disparaissent.
- Q: Est-ce gratuit ?
  A: Oui, sans limite d'utilisation.
- Q: Le fichier est-il envoyé en ligne ?
  A: Non. Il est nettoyé dans votre navigateur.

#### Numéroter ses pièces et obtenir le bordereau de communication en PDF

https://pdf.orihako.com/fr/guide/numeroter-pieces-bordereau/

Numéroter les pièces à la main et taper le bordereau prend du temps, et une erreur de numéro se remarque tard. Ce guide montre comment tout produire d'un coup, sans confier les pièces à un site.

Ce que fait l'outil:
Chaque PDF déposé reçoit un numéro, dans l'ordre que vous choisissez : « Pièce n° 1 » dans un cadre, par défaut en haut à droite de sa première page. Chaque fichier est renommé en commençant par son numéro, par exemple « Pièce n° 1 - Contrat de bail.pdf ».
Le bordereau est produit en PDF (exhibit-list.pdf) et en tableau CSV (exhibit-list.csv), qui s'ouvre dans Excel. La désignation de chaque pièce reprend le nom de son fichier, et le nombre de pages est compté.

Étapes:
1. Nommez vos fichiers comme vous voulez les voir dans le bordereau, par exemple « Contrat de bail » ou « Courrier du 3 mars 2026 ».
2. Ouvrez Numérotation des pièces et déposez toutes les pièces, un PDF par pièce.
3. Mettez-les dans l'ordre avec les flèches : les numéros suivent cet ordre.
4. Dans « Libellé », gardez « Pièce n° 1, 2, 3 », ou choisissez Personnalisé pour écrire par exemple Annexe {n}.
5. Réglez le « Premier numéro » : pour compléter une communication déjà faite, partez du numéro qui suit la dernière pièce.
6. Choisissez la position, puis « Première page » ou « Toutes les pages ». Lancez, puis téléchargez les PDF numérotés et le bordereau.

Avant la communication:
- Relisez le bordereau : corrigez une désignation dans le CSV si un nom de fichier ne convient pas.
- Si une pièce contient des données à masquer, caviardez-la d'abord avec Caviarder (noircir), puis numérotez.
- Par le RPVA, les pièces jointes sont limitées à 4 Mo vers le greffe et 10 Mo entre avocats (vérifié le 15 septembre 2026 auprès d'une source professionnelle). Numérotez d'abord, puis passez les pièces dans la recette « Pièces à transmettre par le RPVA », qui fige, nettoie, compresse et découpe les fichiers trop lourds.
- Suivez les usages de votre juridiction et de votre cabinet pour le format du numéro et du bordereau.

Questions:
- Q: Puis-je numéroter par lettres ou avec mon propre libellé ?
  A: Oui. Choisissez Personnalisé et saisissez un libellé avec {n} pour le numéro ou {A} pour une lettre, par exemple Annexe {A}.
- Q: Mes pièces sont-elles envoyées ?
  A: Non. La numérotation et le bordereau sont faits dans votre navigateur ; vos pièces ne sont pas téléversées.
- Q: Est-ce gratuit ?
  A: Oui, pour un jeu de pièces à la fois. L'enchaîner avec d'autres étapes dans une recette demande Pro.

## How-to articles

The same articles exist in English, Japanese and French; the English text follows.

### Your first run: one tool, one file

https://pdf.orihako.com/howto/first-run/ (ja: https://pdf.orihako.com/ja/howto/first-run/, fr: https://pdf.orihako.com/fr/howto/first-run/)

Every tool works the same way, and every tool is free for single runs. Here is Merge; the steps are the same for all 43 tools.

1. Pick a tool: On the home page, stay on By tool and click a card, or type what you need in the search box.
2. Drop your files: Drag files onto the dashed box, or click it to choose them. The files stay in your browser.
3. Adjust and run: Change the settings if you like, then press Run. Most tools finish in about a second.
4. Download: Download the result, or every result as one ZIP. To keep working on it, pick the next tool under the result.

Tips:
- Merge, Images to PDF and Compare use several files together; other tools take one file per run.
- Settings you use often can be kept as presets under the form.
- Once opened, the site also works offline.

### Use a ready-made recipe for your task

https://pdf.orihako.com/howto/official-recipe/ (ja: https://pdf.orihako.com/ja/howto/official-recipe/, fr: https://pdf.orihako.com/fr/howto/official-recipe/)

Recipes chain several tools for common office work. Pick one by task and run it on one file or many.

1. Choose by task: On the home page, switch to By task and narrow the list by field. Each card shows its steps as small tiles.
2. Read what it does: The recipe page shows the steps in order and what each one changes. Press Open this recipe when it fits.
3. Drop files and confirm: Drop your files. When a step cannot be undone, such as compression, tick the box to confirm; your originals never change.
4. Run and download: Press Run. Each file gets its own result; a file that fails is listed with the step and the reason.

Tips:
- Without Pro, the recipe page lists the same tools to use one by one, for free.
- Change any setting before running: a recipe is a starting point, not a fixed product.

### Build and edit your own recipe

https://pdf.orihako.com/howto/build-recipe/ (ja: https://pdf.orihako.com/ja/howto/build-recipe/, fr: https://pdf.orihako.com/fr/howto/build-recipe/)

When your work is not on the list, build the chain yourself. Everything is tiles and menus; no code.

1. Start: On the recipe page, choose Start empty, or open a recipe and change it.
2. Add steps: Press the + tile and tap tools in the order they should run. Faded tools cannot take what the last step gives.
3. Set each step: Tap a tile to open its settings. Move it with the arrows, or untick Use to keep it without running it.
4. Add a condition: Under Run this step, choose for example “only for scans”: files that already have text skip that step.
5. Name the results: Open Output names and folders and click the chips to build a rule, such as the date and the original name inside year/month folders.
6. See it in motion: The short video shows a recipe built from nothing in under a minute.

Tips:
- The sentence under the tiles always says exactly what will happen.
- View or edit as JSON shows the same recipe as text, for advanced users and AI tools.

### Turn what you just did into a recipe

https://pdf.orihako.com/howto/record/ (ja: https://pdf.orihako.com/ja/howto/record/, fr: https://pdf.orihako.com/fr/howto/record/)

You do not have to plan a recipe. Work as usual, and the steps become one.

1. Run a tool: Use any tool as usual. Under the result, Next offers the likeliest tools; every other one is under Continue in another tool.
2. Continue with the next tool: Tap the next tool. The result goes straight in; there is nothing to download.
3. Open as a recipe: Press Open these steps as a recipe. Name it, save it, and next time run it on many files at once.

Tips:
- Continuing to a second step is where Pro starts. Without Pro, download the result and open the next tool yourself.

### Save, download and share recipes

https://pdf.orihako.com/howto/recipe-files/ (ja: https://pdf.orihako.com/ja/howto/recipe-files/, fr: https://pdf.orihako.com/fr/howto/recipe-files/)

A recipe file holds steps and settings only, so it can be e-mailed or kept on a shared drive safely.

1. Name and save: Give the recipe a name and press Save. It appears under My recipes in this browser.
2. Download the file: Press Download .orihako and share the file like any document.
3. Open a file: Anyone opens it with Open a file, or by dropping it on the box.
4. Read it as JSON: View or edit as JSON shows the same recipe as text; an AI can write one for you there.

Tips:
- Passwords and pictures are never written into a recipe; they are asked for when it runs.
- Installed as an app (Chrome or Edge), Orihako opens a double-clicked .orihako file.

### Process many files at once

https://pdf.orihako.com/howto/batch/ (ja: https://pdf.orihako.com/ja/howto/batch/, fr: https://pdf.orihako.com/fr/howto/batch/)

One file at a time is free. With Pro, a tool or a recipe runs on up to 20 files at once (Business: 200).

1. Drop all the files: Drop the whole set on a tool page or on the recipe page.
2. Run once: Press Run. The progress bar shows which file and which step is running.
3. See what happened: Each file is listed. A file that failed shows the step and the reason, and the others still finish.

Tips:
- Stop after this file ends a long run safely.
- Download all makes one ZIP and keeps the folders a name rule created.

### Automate a folder

https://pdf.orihako.com/howto/folder/ (ja: https://pdf.orihako.com/ja/howto/folder/, fr: https://pdf.orihako.com/fr/howto/folder/)

For offices: put files in one folder and the results appear in another while the page is open. Chrome or Edge on a computer.

1. Open a recipe: Open or build the recipe to apply to every file.
2. Choose the folders: In Automate a folder, choose an input folder and an output folder. The browser asks for permission once.
3. Run now, or keep watching: Press Run now, or tick the box to process new files every few seconds while the page is open.
4. Check the results: Results follow the recipe's folder rule. Failed files are copied to _failed with the reason, and orihako-log.csv lists every run.

Tips:
- Files already processed are recognised by their content and skipped, even if renamed.
- For runs at night, use the command line from the AI agents tab with a scheduled task.

### Use Orihako from an AI agent

https://pdf.orihako.com/howto/agents/ (ja: https://pdf.orihako.com/ja/howto/agents/, fr: https://pdf.orihako.com/fr/howto/agents/)

The agent runs on your computer, so the AI never receives your files.

1. Two ways to connect: Open the AI agents tab: one card for Claude Desktop, one for every other app. Take the one for the app you use.
2. Claude Desktop: one file: Press Download orihako.mcpb, double-click the file you get, and press Install in the window that opens. No Node.js to install: Claude Desktop brings its own.
3. Other apps: one command: Unzip orihako-agent.zip, open a terminal in that folder and run “node orihako.mjs setup”. It adds Orihako to the Claude Code, Cursor and VS Code it finds (Node.js 20 or later).
4. Ask: Restart the app, then ask in plain words, for example “compress every PDF in Downloads to under 3 MB”. The agent answers with what it did.

Tips:
- One tool on one file is free; chains and many files need a Pro key (activate_license).
- To undo it, run “node orihako.mjs setup --remove”. A settings file is copied beside itself before it is changed.
- Nothing to install: copy the recipe prompt into any AI chat, then paste the answer into the recipe page.

### Buy Pro or Business and turn it on

https://pdf.orihako.com/howto/plans/ (ja: https://pdf.orihako.com/ja/howto/plans/, fr: https://pdf.orihako.com/fr/howto/plans/)

Every tool stays free. Pro adds chaining and batches; Business adds folder automation and logs.

1. Compare plans: Open Pricing to see what each plan adds, side by side.
2. Buy: Press the plan's button. Payment happens on our payment partner's page, which e-mails a receipt.
3. The key is filled in: After paying you come back to Pricing with the key filled in, and it activates by itself. The key is in the e-mail too.

Tips:
- A lifetime key bought before is Pro now, at no cost.
- To use the key on another computer, remove it on Pricing in the old browser first.

## Agent tools

The desktop agent is an MCP server on the person's own computer: https://pdf.orihako.com/agents/ (ja: https://pdf.orihako.com/ja/agents/, fr: https://pdf.orihako.com/fr/agents/). Claude Desktop installs https://pdf.orihako.com/downloads/orihako.mcpb with a double-click; https://pdf.orihako.com/downloads/orihako-agent.zip (Node.js 20 or later) sets up Claude Code, Cursor and VS Code with "node orihako.mjs setup".

What the server tells the assistant: Orihako processes PDF files on this computer; the files are never uploaded. Start with list_tools or list_recipes. One tool on one file is free. Chaining steps, several files, conditions and name templates need an Orihako Pass Pro or Business key, or a PDF Pro or Business key (activate_license); the 7-day pass is for the websites only. A recipe is JSON: {"format":"orihako.recipe","version":1,"name":...,"steps":[{"tool":id,"values":{...},"when":{...}}],"input":{"mode":"each"|"together"},"output":{"name":"{name}_{date}","folder":"{yyyy}/{mm}"}}. Check a recipe with validate_recipe before run_recipe. Steps that cannot be undone (redact, flatten, compress...) need confirm_irreversible: true after asking the person. Results are written to output_dir; originals are never changed. Tools that answer with a report or a list (leak-check, exhibits, bundle, e-invoice, bates) run through run_tool on their own; they cannot be a recipe step. Before sending a file out, leak-check says what it still carries (hidden text, earlier versions, metadata, comments, attachments). AI Mask: before the content of a file the person names reaches this conversation, mask it with mask_file (company and people's names from the person's word list, phone numbers, addresses, amounts... become placeholders such as 【会社A】 or 【Company A】). Do not open the original yourself. Ask the person to read the masked file; read it (or call again with return_text: true) only after they say yes. (mask-for-ai in list_tools is the website's page; here use mask_file.) Keep every placeholder exactly as written in your answer. Put the real values back with restore_to_file: it writes the answer into a file for the person and returns only its path. Never ask for the restored text and never read that file: this conversation goes to an outside AI. 27 of the 43 tools run here. These 16 read or draw the pages with the browser's PDF reader and need the browser: pdf-to-images, crop, remove-blank, split-bundle, summarize, pdf-to-word, pdf-to-text, pdf-to-table, read-aloud, ocr, redact, mask-for-ai, proofread, scan-check, compare, rename-invoices. Send the person to https://pdf.orihako.com/<tool>/.

Tools:
- list_tools (List PDF tools): Every Orihako tool with what it takes and gives, whether it runs here, and whether its result can be undone.
- describe_tool (Describe a tool): One tool's settings as a JSON Schema (the same fields as its page), to fill `values` for run_tool or a recipe step.
- inspect_pdf (Inspect a PDF): Page count, whether the PDF has a text layer (false means a scan that needs OCR), encryption and size.
- run_tool (Run one tool): Runs one tool on files and writes the results to output_dir. Free for one file; several files into a one-file tool is a batch (Pro).
- list_recipes (List official recipes): Ready recipes for common office work (sending invoices, contracts for outside parties, scans...), each with its recipe JSON to run or adapt.
- validate_recipe (Validate a recipe): Checks a recipe and returns every problem with the step it concerns, or a one-line summary, the steps that cannot be undone and what plan it needs.
- run_recipe (Run a recipe): Runs a recipe (JSON or a .orihako file) on files; each file's chain runs on its own and a failure stays with that file. Needs Pro for two or more steps.
- mask_text (AI Mask a text): Replaces what should not reach an AI in a text (company and people's names from the person's word list, phone numbers, e-mail and postal addresses, account and card numbers, amounts) with placeholders such as 【会社A】【人1】【電話1】; the same value keeps the same placeholder. Returns the masked text, a key_id and counts. The key that puts an answer back is kept 30 days on this computer. For a file, use mask_file instead: this text is already in the conversation.
- mask_file (AI Mask a file): Reads a PDF with a text layer, a Word file (.docx) or a text file (.txt, .md, .csv) on this computer, masks it as mask_text does, and writes <name>-AIマスク.txt (en: -ai-masked, fr: -masque-ia) beside it (or into output_dir). Returns the file's path, a key_id and counts, not the text. Scans (no text layer), old .doc files and files with a password are refused with what to do. Set return_text: true only after the person has read the masked file and said it may be used.
- list_words (AI Mask word list): How many words the person's AI Mask word list holds, by kind, and the file it is in. The words themselves are not returned (they are what is hidden from the AI). Give word to learn whether that one word is listed.
- add_word (Add a word to the AI Mask list): Adds a company, person, project or product name to the person's word list on this computer, so every later masking hides it. Ask the person first.
- restore_to_file (Put the real values back, into a file): Puts the real values back into an answer that holds AI Mask placeholders and writes it to a file for the person; returns only the file's path and counts, never the restored text. Without key_id the kept key the answer fits is used; when it fits several, the error lists them: ask the person which one.
- license_status (Licence status): The plan active on this computer and what it allows.
- activate_license (Activate a licence key): Activates a licence key from the purchase e-mail on this computer (uses one of the key's seats): an Orihako Pass Pro or Business key, checked at orihako.com, or a PDF Pro or Business key. The 7-day pass is for the websites only.

Prompts:
- check_before_sending (Check a file before sending it): Runs the leak check on a PDF and says, in plain words, what to remove before it goes out.
- shrink_for_email (Make a PDF small enough to e-mail): Inspects a PDF, compresses it to a size limit and reports what it cost.
- write_recipe (Write a recipe for repeated work): Turns a described job into an Orihako recipe, checked before it runs.
- mask_before_sending (Mask a file before the AI reads it): AI Mask: replaces names, numbers and amounts in a PDF, Word or text file with placeholders on this computer, so only the masked text reaches the AI; the answer is put back into a file for you.

27 of the 43 PDF tools run in the agent on the computer: merge, split, rotate, delete-pages, reorder, images-to-pdf, remove-metadata, compress, fit-mail, fill-sign, sign-return, resize-pages, n-up, halve-pages, flatten, extract-images, bookmarks, bundle, watermark, page-numbers, bates, exhibits, stamp, protect, unlock, leak-check, e-invoice.
16 need the browser, because they read or draw the pages with the browser's PDF reader (the agent sends the person to the tool's page): pdf-to-images, crop, remove-blank, split-bundle, summarize, pdf-to-word, pdf-to-text, pdf-to-table, read-aloud, ocr, redact, mask-for-ai, proofread, scan-check, compare, rename-invoices.

Other sites (Orihako Chat among them) run tools through the /embed/ page, documented at https://pdf.orihako.com/api/. It always runs as the free plan and offers: merge, split, compress, images-to-pdf, pdf-to-images, remove-metadata, leak-check, fit-mail, pdf-to-word, pdf-to-text, pdf-to-table, read-aloud, rotate, delete-pages, reorder, crop, resize-pages, n-up, halve-pages, remove-blank, flatten, bookmarks, extract-images, ocr, mask-for-ai, scan-check, proofread, compare, page-numbers, bates, exhibits, bundle, protect, unlock, watermark, stamp, split-bundle, rename-invoices, e-invoice.
