Add a password to a PDF

Set a password so only people who know it can open the PDF. Your file and password never leave your device.

How it works

  1. Pick your PDF

    Drop the file or choose it from your device. Nothing is uploaded.

  2. Pick a setting

    Type your password twice and encrypt.

  3. Download

    Save the finished file or carry on with another PDF tool.

What this tool does

Encrypting private PDFs such as IDs, contracts or health records before emailing them is a good habit. The file needs the password to open.

Encryption runs on your device with 256-bit AES. If you forget the password, there is no way to open the file again; we do not know your password either, so write it down.

Frequently asked questions
