How to put a password on a PDF

Sending a payslip, bank statement or personal paper? Add a password. Only someone who knows it can open the file.

The Password protect PDF tool encrypts the file with AES-128. It runs in the browser; the file and password are not sent anywhere.

  • Open nibrascode.com/en/pdf/protect.
  • Choose the PDF.
  • Type the password.
  • Download the protected PDF.

Keep the password. If you forget it, it cannot be recovered. Do not send the password in the same message as the file.
