Protect with password
Encrypt a PDF so it asks for a password when opened.
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.
Your files are never uploaded.
How to use it
- Drop one PDF file.
- Type the password readers will need. Optionally add a different owner password.
- Press Run and download the protected PDF.
Questions and answers
Which apps can open the protected file?
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.
What is the owner password for?
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.
Is the password sent anywhere?
No. It is only used on this device to encrypt the file, and it is not stored.
