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.
Encrypt before you send
Bank details, agreements and ID proofs are safest with a password. Once protected, the PDF cannot be opened without the password, even if the email is forwarded.
You choose the password
Pick a strong password you will remember. It is applied as real encryption, not just a hidden setting.
Keep the password safe
We cannot recover a lost password for you, so store it somewhere secure. Your files are processed temporarily and deleted automatically — there is no general cloud storage.
