How the browser process works

Remove the open password from a PDF you own by decrypting and rebuilding it. The page sends the selected file and settings to its pdf-unlock browser engine, creates a new output and downloads it without overwriting the source.

Only use this on documents you are authorised to unlock. You must know the password.

Privacy, quality checks and limitations

  • Keep the original file until the downloaded output has been opened and checked.
  • Verify page count, orientation, dimensions, text legibility, audio/video duration and metadata relevant to your use.
  • Browser-local processing reduces routine upload exposure, but your device, browser extensions and download location still matter.
  • A converted preview is not proof of legal authenticity, archival compliance, accessibility or digital-signature validity.

Remove a known open password from a PDF you are authorised to unlock. The current browser tool requires the correct password and rebuilds the document through its existing PDF workflow.

When can you unlock a PDF?

  • You own the document or have permission to access it.
  • You know the current password used to open the PDF.
  • You need a copy without the open-password requirement.

Security note

This tool is not intended to bypass unknown passwords. Only use it with documents you are authorised to unlock.
