256-bit AES encryption ensures your PDFs are protected with the same security used by governments.
Control exactly what users can do - printing, copying, editing, annotations, and more.
Fast local encryption means your files are protected in seconds, not minutes.
How secure is the password protection?
We use 256-bit AES encryption, the same standard used by banks and governments. This is virtually unbreakable with current technology.
Can I remove the password later?
Yes, use our PDF Unlocker tool to remove passwords from protected PDFs if you have the original password.
Do permissions really prevent unauthorized actions?
Permissions provide good protection against casual users, but determined users with specialized tools may bypass them. The password encryption is the primary security layer.
Are my files stored on your servers?
No, all encryption happens locally in your browser. Your original and protected files never leave your device.
