Add a password (AES-256). Encrypted on your device.

🔒 On your device

How to use it

  1. Drop the PDF you want to encrypt.
  2. Type a password of at least 4 characters (longer is far safer).
  3. Press Protect PDF and download the encrypted file.

Troubleshooting

I lost the password.

It cannot be recovered. Encryption happens on your device and we never see the file or the password — keep a copy of the original.
