Frequently Asked Questions
Upload your protected PDF, enter the current password, and click unlock. The decrypted PDF downloads without any password restrictions.
No. MiOffice requires the original password. We do not crack, brute-force, or bypass PDF encryption — that would be a security tool, not a productivity tool.
Yes, as long as you have authorization to access the document. This tool is designed for unlocking your own password-protected files.
No. Decryption runs entirely in your browser. Your PDF and password never leave your device.
Standard PDF password protection (both user and owner passwords). Files encrypted with certificate-based security or DRM are not supported.
Up to 100MB per PDF file. No daily limits on how many files you unlock.
Yes. The output PDF has no password, no print restrictions, and no edit restrictions. It is a fully open document.
That is an owner password restriction. Upload the PDF and it will be decrypted to remove those restrictions. No password needed for owner-only locks.
Yes. Unlock the PDF here, then use our Protect PDF tool to add a new password and permission set.
Double-check the password — it is case-sensitive. If the file uses certificate-based encryption or DRM, this tool cannot process it.
