Free PDF Unlocker
Free PDF unlocker tool to remove password protection from PDFs.
Free PDF Unlocker is a free online tool that removes password protection from PDF documents when you know the correct password. Enter the owner or user password, and the tool instantly decrypts the file, removing all restrictions on printing, copying, editing, and form filling. The decrypted PDF retains its original quality, formatting, fonts, and images — no content is altered or lost during the process. All processing happens locally in your browser — your PDF and password are never uploaded to any server. There is no file size limit, no sign-up, and no watermark added. It is ideal for unlocking PDFs that you own but have forgotten the permissions password for, removing print restrictions from documents you are authorized to access, unlocking forms that cannot be filled, or preparing a document for editing when it was saved with restrictions. The tool supports both 40-bit RC4 and 256-bit AES encrypted PDFs. Works on Windows, Mac, Linux, iOS, and Android in any modern browser.
