PDFKey Pro

PDFKey Pro is a macOS and Windows utility that removes password protection from PDF files. It can create an unlocked copy of a document without requiring the copying or printing password, and, when a viewing password is known, it can also generate a fully unlocked version. The software supports processing multiple files or entire folders by dragging them onto the application, and it includes command‑line tools for integration into automated workflows.

The tool is aimed at users who have lost or forgotten PDF passwords and need to regain access to the content or to remove usage restrictions for printing and copying. It also offers the ability to apply new passwords and usage restrictions, allowing users to protect PDFs with separate view and permission passwords.

Features include bulk processing, automatic update checks via UpdateFX, and a multilingual interface supporting English, Italian, French, Russian, German, Polish, and Dutch. The program creates output files that are identical to the originals and compatible with any PDF viewer.
