All Encryption Types Supported
Handles RC4, AES-128 and AES-256 encrypted PDFs. Owner-password PDFs unlock instantly. User-password PDFs need the password entered — then all encryption is removed regardless of type.
100% Private — No Upload
All unlocking happens entirely inside your browser. Your PDF is never sent to any server, never stored and never seen by anyone else. Completely private.
Instant — No Quality Loss
For owner/RC4/AES-128 PDFs, unlocking only removes password metadata — all content preserved. For AES-256 PDFs, pages are rendered at 2× resolution for maximum quality.

Frequently Asked Questions
How do I unlock a PDF online for free?
Upload your PDF. If it only has an owner password (restrictions), it unlocks instantly — no password needed. If it requires a password to open, enter the password and click Unlock PDF. Your unlocked document downloads instantly, free with no sign-up and no server upload.
What is the difference between a user password and an owner password?
A user password (open password) is required to open the PDF at all — without it the file cannot be read. An owner password restricts what you can do with an already-open PDF (printing, copying, editing) but the file can still be opened without a password. Owner-protected PDFs unlock instantly. User-password PDFs require the correct password to be entered.
Can I unlock a PDF without knowing the password?
If the PDF only has an owner password (print/copy/edit restrictions), it can usually be unlocked without a password using this tool. If the PDF requires a password just to open it (user password), you must know the correct password — this tool cannot bypass user passwords.
Is it safe to unlock a confidential PDF in my browser?
Yes — because everything runs locally in your browser using pdf-lib and PDF.js, your confidential document never leaves your device. There is no network request, no cloud processing and no data retention of any kind. It is safer than any server-based PDF tool.
Does unlocking reduce the PDF quality?
For owner-protected and RC4/AES-128 user-password PDFs, unlocking only removes the password metadata — all content, images, fonts and formatting are preserved exactly. For AES-256 encrypted PDFs, pages are rendered at 2× resolution using PDF.js and rebuilt as high-quality images, so quality remains excellent though text will not be selectable.
After unlocking, how do I reduce the file size or add security back?
Once unlocked you can use our free PDF compressor to reduce the file size before sharing. If you later want to re-apply password protection, our free PDF protector lets you add an open password and set printing, copying and editing restrictions — all in your browser with no sign-up.
