Frequently Asked Questions

Can I unlock a PDF without the password?

No. This tool doesn't crack passwords — you need to know the open password. If a PDF only has permission restrictions (no open password), leave the field blank.

What's the difference between open and permission passwords?

The open password is required to view the file. The permission (owner) password only restricts printing, copying, etc. Both are removed here.

Is anything uploaded?

No. Decryption happens in your browser — your file and password never touch a server.

Will formatting change?

No. The PDF is saved byte-preserving apart from the encryption dictionary — pages, fonts, images and annotations are untouched.

Is this legal?

Yes, for PDFs you own or have permission to modify. Don't remove protection from documents you aren't authorized to change.
