常见问题解答

Can this crack a password I don't know?
No. You must enter the correct existing password — this tool removes encryption from a file you already have legitimate access to, it does not break or guess passwords.
Is it legal to unlock a PDF?
Only unlock PDFs you own or have explicit permission to access without restriction. Removing protection from a document you don't have rights to may violate the law or the document owner's terms.
Does unlocking reduce the file quality?
No. The content is unchanged — only the password encryption layer is removed.
