자주 묻는 질문
Is this unlock tool free?
Yes, completely free with no usage limits.
Can it remove the password without knowing it?
No. You must know the password — we use it to decrypt the PDF locally. We are not a "crack" tool.
Does the password leave my browser?
Never. The password is used by PDF.js inside your browser to decrypt, then we re-save without encryption. No network call involved.
Will the resulting PDF look identical?
Yes. The visible content is unchanged. Only the encryption layer is removed.
Does it work offline?
Yes, after the first visit.
