Unlock a PDF and remove its password
Unlock PDF files free in your browser. Remove the password and encryption from a PDF you can open, then download an unprotected copy. Private, no upload, no sign-up.
100% private — files never leave your deviceYou must know the password — this removes protection you're allowed to remove, it doesn't crack unknown passwords.
How to use
- Upload your protected PDF. Select or drag in the password-protected PDF you want to unlock. It loads straight into your browser and is never uploaded.
- Enter the password. Type the password you already use to open the file. MuPDF uses it to decrypt the document locally on your device.
- Download the unlocked PDF. Save a copy with the password and encryption removed, ready to open, share, or archive without a prompt.
Features
- Nothing leaves your device. The PDF is decrypted and rebuilt in your browser with MuPDF, so a sensitive or confidential file is never uploaded to any server.
- No more password prompts. The output opens instantly with no password and no encryption, so you and your recipients never have to type it again.
- Keeps your content intact. Only the password protection is removed. The pages, text, images, and layout stay exactly as they were.
- Free with no sign-up. Unlock as many PDFs as you like at no cost, with no account, no email, and no watermark on the result.
- Fast, in-browser decryption. Powered by MuPDF compiled to WebAssembly, the unlock runs locally and finishes in seconds with no upload wait.
When to use it
- Remove the password from a confidential bank or tax statement you own so you stop retyping it every time
- Save an unprotected copy of a payslip or invoice before forwarding it to your accountant
- Strip the open-password from a contract you are authorised to access so it archives cleanly
- Unlock a personal scan or medical document for your own records without uploading it anywhere
- Prepare a protected PDF for a tool or workflow that cannot handle encrypted files
Is it private?
Your PDF is decrypted and rewritten locally in your browser with MuPDF and is never uploaded to any server.
Frequently asked questions
Is this PDF unlocker free?
Yes. Unlocking PDFs is completely free with no sign-up, no account, and no email required, and there is no watermark on the output.
Are my PDFs uploaded to a server?
No. Your PDF is decrypted and rewritten entirely in your browser using MuPDF, so it is never uploaded. The file stays on your device the whole time, which makes it safe for confidential documents.
Can it crack or bypass a password I do not know?
No, and it is not designed to. You must enter the correct password yourself. The tool only removes protection from a file you are authorised to open; it cannot guess, crack, or bypass an unknown password.
What does unlocking actually remove?
It removes the password and encryption from the PDF, so the saved copy opens without asking for a password. The page content itself is left unchanged.
What if my PDF only restricts printing or editing, not opening?
If the file opens without a password but limits actions like printing or copying, those permission settings are tied to the owner password. Enter that owner password to produce a copy with the restrictions removed.
Are there any file size or format limits?
It works with standard PDF files and runs locally, so there is no server-side upload cap. Very large PDFs depend on your device's available memory, since all processing happens in your browser.
