Frequently asked questions

Can this tool unlock any password-protected PDF?
No. You must provide the correct password to unlock the PDF. This tool decrypts a PDF using the password you supply. It cannot bypass unknown passwords.
Is it legal to remove the password from a PDF?
Only if you own the document or have explicit permission from the owner. Removing password protection from documents you do not have rights to access is not permitted.
My PDF is locked but I cannot remember the password. Can the tool help?
Not without the password. If you genuinely own the document and have lost the password, some PDF recovery tools attempt to recover it, but this is a separate capability from this tool.
Does unlocking reduce quality or change the content?
No. Unlocking only removes the encryption layer. The content, layout, and quality are identical to the original protected version.
Is my PDF uploaded to a server?
No. Processing happens entirely in your browser. Your document never leaves your device.
After unlocking, can I re-protect with a different password?
Yes. Use the PDF Protect tool on the unlocked version to apply a new password.
