From the developer:
Compare two PDF documents - fast, incredibly easy and reliably. Just drop two PDF icons into the PDiff window… and instantly see the comparison results. Comparing texts has never been this easy.
What exactly has changed, what is really the same? How often do you get back a document and are still uncertain about the changes? Why is it such a hard task to juggle with revisions edited by many authors?
