Compare two PDF documents.

In English
Version 2.3.2
Based on 1 user rate

PDiff Express overview

PDiff Express allows one to compare two PDF documents quickly and reliably.

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? If you just want to *see* what happened, then PDiff Express is made for you!

PDiff Express allows you to compare the content of two PDFs in order to pinpoint all textual changes. Just drag and drop two versions into PDiff and you will see all differences at a glance. This still works if fonts, layout, hyphenation or even page breaks were altered.
