Why use our Protect PDF
Secure & private
Files are encrypted in transit and deleted automatically after processing.
Fast results
Optimized processing returns your file in seconds.
Free to start
Core tools are free with daily limits — no install required.
Works anywhere
Runs in your browser on any device, anywhere in the world.
Phone sharing, protected
Documents fly off phones fast — Mail, WhatsApp, AirDrop — often faster than protection gets considered. The Safari encryption inserts the thirty-second lock between "attach" and "send" for the files that warrant it.
The iPhone mechanics
Save or locate the PDF in Files, encrypt in Safari, share the locked copy from Downloads — and message the password separately, which on a phone is one app-switch away.
