About Protect PDF
Encryption happens in your browser with AES-256 — your file and password never leave your device. Anyone opening the file will need the password.
How it works
- Add your pdf — drag and drop or browse.
- Choose your settings.
- Click the action button and wait a moment.
- Download the result. Nothing was uploaded.
