Password protect a PDF
Add a password to a PDF in your browser. The file is encrypted with AES, so it opens only with the password you choose. Nothing is uploaded.

Good to know
- A forgotten password cannot be recovered, here or anywhere else. Keep it somewhere safe.
- Files that are already password protected must be unlocked first.
Frequently asked questions
- How do I put a password on a PDF?
- Add the PDF, type a password twice, and choose Protect PDF. The encrypted copy downloads and asks for that password when opened.
- Is my password sent anywhere?
- No. Encryption happens in this tab and the password is never stored or transmitted.
