About this tool
Lock a PDF so it needs a password to open. Encryption uses AES-256, and you can also restrict printing and copying. Because everything runs in your browser, neither the file nor the password is sent anywhere.

What if I forget the password?
There is no recovery. Keep the password in a password manager before sharing the file.
