Encrypting or decrypting a PDF

The “Add” mode encrypts your PDF with AES-256 : the password will be required to open it. The “Remove” mode strips the protection from a PDF whose password you know. The security engine (~10 MB) is downloaded once on first use.

Frequently asked questions

Is my password transmitted ?

Never. Encryption happens 100 % inside your browser ; neither the file nor the password leaves your device.

What happens if I forget the password ?

An encrypted PDF cannot be opened without its password. Keep it somewhere safe : there is no way to recover it.
