Learn how to use password protect. 100% free, no installation required.

Password protection encrypts a PDF so only someone with the password can open it. It is the right control for a payslip, a contract or an ID scan that has to travel by email.

  1. Upload Files

    Add the PDF you want to encrypt.

  2. Set Options

    Set the password. Optionally restrict printing, copying or modification separately from the open password.

  3. Download

    Download the protected file, then send the password through a different channel from the document itself.

Tips & Best Practices

  • Never email the password alongside the file. Send it by message or phone — otherwise the encryption achieves nothing.
  • There is no recovery. Forget the password and the document is gone, so store it before you send anything.
  • Permission restrictions are enforced by the viewer, so they deter casual copying rather than guarantee it. Only the open password provides real protection.
  • Encryption is applied in your browser, so neither the file nor the password crosses the network.
