About this tool

You are about to email a medical record, a bank statement or a contract. With a password, even if the email reaches the wrong person, the file won't open.

Most sites that add a password upload your document to their server first — the opposite of what you want. Here encryption runs in your browser and the file never leaves your computer.

How it works

  1. 1

    Drop the PDF.

  2. 2

    Type a password or press “Create a strong one”.

  3. 3

    Download the protected PDF and share the password through another channel.

Questions

Which encryption does it use?
AES-256, the strongest in the PDF standard. Adobe Acrobat, Chrome, Edge, macOS Preview and mobile readers open it.
What if I forget the password?
It cannot be recovered: we never see or store it. That's why you can copy it with one click.
Why send the password separately?
If both travel in the same email, whoever intercepts it has both. Send it by chat or say it on the phone.
