How it works

Unlock your PDF in three steps

  1. 1

    Upload your password-protected PDF

    Drag and drop your PDF onto the tool or click to browse. The file loads in your browser — never sent to any server.

  2. 2

    Enter the current password

    Type the document's current password. The mupdf WASM module verifies it locally and decrypts the document.

  3. 3

    Download the unlocked PDF

    Click 'Download unlocked PDF'. The decrypted file downloads immediately — no password required to open it.

Why use Signvoy

Fast, secure, private

Requires the correct password

The tool verifies the password using mupdf WASM before decrypting — it cannot bypass encryption without the right password.

Instant unlocked download

Decryption runs locally using WebAssembly and the unlocked PDF downloads in seconds — no queue, no server round-trip.

Your file and password stay local

Everything runs in your browser. Your PDF and your password are never sent anywhere — close the tab and both are gone.

FAQ

Common questions

Can this tool unlock any PDF without a password?
No — the tool requires the correct current password. It cannot bypass encryption. Only use this on PDFs you own and have the password for.
Is it legal to remove the password from a PDF?
Yes, if you are the owner of the document or have been given the password by the owner. Removing password protection from documents you do not have rights to may be illegal.
My password is correct but it's still failing — why?
Some PDFs use XFA or non-standard encryption that mupdf may not support. If the tool fails consistently with the correct password, the PDF may use an unsupported encryption method.
Will the unlocked PDF retain all content?
Yes — decryption removes only the encryption layer. All text, images, and formatting are preserved exactly as in the original.
