Unlock PDF is a free online tool that removes the password from a PDF you have the right to access, so the document opens directly without a prompt.
Remove a known password
When you own a protected PDF and know its password, retyping it every time is tedious. Unlock PDF uses the password to decrypt the file once and saves an unprotected copy, so it opens instantly from then on across all your devices.
Only for documents you own
Unlock PDF requires the correct password to remove protection; it does not bypass or crack encryption. Use it only on files you are authorized to access, such as your own statements or documents shared with you legitimately.
How To Use Unlock PDF
- Open Unlock PDF in your browser.
- Drop your protected PDF onto the upload area.
- Enter the current password.
- Confirm to remove the protection.
- Download the unlocked PDF.
