The program removes copying and printing passwords if they have been forgotten. It also removes viewing passwords from PDF documents if the password is provided beforehand. It can also operate in batch mode using command-line and included Automator tools. PDFKey Pro is not designed to defeat DRM systems and will not decrypt eBooks or protected materials.
This program requires Mac OS X 10.2 or later. In the evaluation mode, PDFKey Pro only partially decrypts PDF documents. A registration reminder appears every 10 minutes.
