Frequently Asked Questions

What encryption formats are supported?

This tool supports removing passwords from widely used encryption standards (128-bit RC4, 128-bit AES), which cover almost all older and modern files. Next-generation AES-256 is not universally supported directly in standard client-side decryption.

What if I enter the wrong password?

The tool will tell you the password is incorrect. It cannot crack or bypass passwords — you must know the correct password to unlock the PDF.

Does my file get sent to a server?

No. All decryption runs in your browser. Your file never leaves your device.

Can this remove DRM or copy protection?

No. This tool only removes standard PDF password protection when you provide the correct password. It cannot bypass rights management systems.

What should I do if unlocking fails on a valid password?

Try the owner password if you used a user password. Some modern PDFs use newer unsupported encryptions.
