The Complete Guide to PDF Passwords

Why password-protect a PDF?

Password protection prevents unauthorized access to sensitive documents — contracts, financial records, personal information, or confidential reports.

Unlocking removes the password so you can freely open, print, or edit the PDF without entering credentials each time.

How the pdfcut.app password tool works

The tool uses the PDF specification's built-in encryption. To unlock, it loads the PDF with your password, then saves a new unencrypted copy. To protect, it loads an unprotected PDF and saves it with password encryption. Everything runs in your browser.
