Frequently Asked Questions
What is the difference between Protect and Encrypt?+
Both tools add password protection. The Protect tool provides a simple interface for basic password protection. The Encrypt tool offers advanced options including AES-256 encryption and granular permission controls.
Can I allow printing but prevent editing?+
Yes. You can set permissions that control exactly what recipients can do with the PDF — open, print, copy text, or edit — independently.
Is my password processed on a server?+
No. Password protection is applied entirely in your browser. Your password and document never leave your device.
