Protect PDF with Password — Overview
What is Protect PDF with Password?
Protect PDF adds a genuine open password to a PDF: without it the document cannot be read at all, because the page content itself is encrypted rather than merely hidden behind a setting.
You can also set owner permissions that decide what a reader may do once the file is open — printing, copying text, editing content, commenting, filling forms and rearranging pages.
Encryption runs entirely in your browser. Neither the document nor the password is transmitted, which makes it usable for payslips, medical letters, board papers and client files.
What does Protect PDF with Password do?
Real encryption with practical controls:
- Open (user) password required to view the document
- Optional separate owner password for full rights
- Six independent permission switches
- Live password strength meter with concrete advice
- Confirmation field so a typo cannot lock you out
- Accessibility extraction left enabled so screen readers still work

Privacy & cost
This tool runs entirely in your browser. Nothing is uploaded, logged, or saved on our servers — safe for confidential or proprietary data.
Where it fits
Encrypt a payslip or medical report before attaching it, and share the password through a different channel.
Allow printing but block copying so your pricing cannot be lifted straight into a competitor's document.
Turn off editing and page assembly so a circulated pack cannot be quietly rearranged.
