Frequently Asked Questions
Is my locked password kept safe on your servers?
Completely. Because the lock encryption compiles locally on your own machine sandbox, we never transmit passwords or file contents to cloud servers.
Can I remove the password security lock later on?
Yes. You can use our sister tool "PDF Unlocker" to easily strip protection from any PDF document you hold authorized passwords for.
What cryptographic standard does this lock utilize?
Our encryption implements high-strength RC4/AES standard security, ensuring compatibility across all major PDF readers including Adobe Acrobat.
