What is special about PDiff Professional?

PDiff Professional allows interactive comparison of PDF files. In addition, you can load other common document formats… so you can also compare data from a word processor with corresponding PDF files.

Automate PDiff Professional to handle large quantities of documents or to repeatedly examine files. You can even execute PDiff Professional from your existing software, like a workflow system.

In addition to machine-readable XML output, you can generate proof reports as PDF. These reports dcoument all changes and similarities, including exact details of matching/disagreeing text passages, their position in the documents tested, and even a graphical display of the relevant PDF pages.
