Unlock PDF Online — Remove Password Protection, Free and Private

Unlock PDF is a free, browser-based tool for removing the password from a PDF file you have access to. Drag in your protected PDF, enter the password that opens it, and save a copy that no longer requires a password to open. The original file on your device is not modified.

You need to know the password to unlock a PDF with CanaryPDF. The tool does not crack or bypass PDF password protection — if you've lost a password to a document you own, the file cannot be recovered. For documents shared with you, ask the sender for the password.

Your PDF stays on your device. CanaryPDF processes the file entirely in your browser using WebAssembly — there are no uploads to any server, no password transmission, and no account required. Closing the tab erases all working state.

Common reasons to remove a PDF password include: sharing documents internally where password enforcement is no longer needed, archiving owned documents for easier reading, processing PDFs with tools that don't handle encryption, or removing friction on files you open frequently.

Unlocking removes both the user password (required to open the file) and the owner password (which controls permissions like printing, copying, and editing). The resulting PDF has no restrictions. If you want to re-protect the file later with a different password, use the Protect PDF tool.

If you want to keep the password protection but change it to a new password, unlock the file here, then open the Protect PDF tool to set a new password. The Unlock PDF tool supports standard PDF encryption, including AES-128 and AES-256.

How to Unlock a PDF

  1. Open the Unlock PDF tool — Go to canarypdf.com/unlock-pdf or click Open PDF on this page to get started.
  2. Select your password-protected PDF — Click Open PDF or drag a password-protected PDF file into the upload area. CanaryPDF detects the encryption automatically.
  3. Enter the PDF's password — Type the password that opens the file. CanaryPDF does not crack passwords — you need to know the password to unlock the document.
  4. Save the unlocked PDF — Click Save to download a copy of the PDF that no longer requires a password. The original file on your computer is unchanged.

Frequently asked questions

How do I remove the password from a PDF?
Open the Unlock PDF tool and select your password-protected PDF. Enter the password when prompted, then click Save. CanaryPDF produces a copy of the PDF that no longer requires a password — the original file on your device is not modified.
Can I unlock a PDF without knowing the password?
No. CanaryPDF requires the password to unlock a PDF — it does not crack or bypass password protection. If you've lost a password to a document you own, the file cannot be recovered without it. For documents shared with you, contact the sender.
Is my PDF uploaded to a server when I unlock it?
No. CanaryPDF processes your PDF entirely in your browser. Your file is never uploaded to a server, and your password is not transmitted anywhere. Decryption happens locally using WebAssembly.
What is the difference between a user password and an owner password?
A user password (also called the 'open password') is required to open and view the PDF. An owner password controls permissions like printing, copying, and editing. Unlocking removes both, producing a PDF with no password restrictions.
When does it make sense to remove a PDF password?
Common cases: sharing a document internally where the password no longer needs to be enforced, archiving documents you own, processing PDFs in other tools that don't handle password-protected files, or simply removing friction for files you access frequently.
Is the unlocked PDF safe to share?
The unlocked PDF has no password protection, so anyone who receives it can open and read its contents. If you need to share a sensitive document, consider keeping the password or using the Protect PDF tool to set a new password before sharing.
Does it work on scanned or image-based PDFs?
Yes. The Unlock PDF tool works on any password-protected PDF — text, image, scanned, or mixed — as long as you have the password. The PDF's internal content type does not affect unlocking.
