Add Password to PDF
Encrypt a PDF with a password in your browser so only people with the password can open it.
Runs in your browser — files never leave your device
How it works
Protect a PDF so it can only be opened with your password.
Encryption runs locally with AES, so the document and password stay on your device.
Frequently asked questions
- Is my PDF or password uploaded?
- No — the PDF is encrypted in your browser and the password never leaves your device.
- What encryption is used?
- Standard PDF AES encryption. Anyone opening the file will be prompted for the password.
- What if I forget the password?
- There’s no recovery — store it safely. The encryption is real, not a trick.
