よくある質問 (FAQ)

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.
