Password protect a PDF

Lock a PDF with a password using strong AES-256 encryption.

or drop a PDF here

🔒 Free. Try any tool right away; a free account saves your work. Your file stays on your device: nothing is uploaded.

How it works

  1. Open the PDF
  2. Choose a password
  3. Download the locked file

Private by design

Quick PDF runs entirely in your browser. Your PDFs are opened, edited and saved on your own phone or computer. They are never sent to a server, so nobody (us included) can see them. It even works offline once loaded.

Questions

Can you recover a forgotten password?

No. We never see your file or your password, so keep it somewhere safe.
