How can I compare 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 is made for you!

Even for long documents you see the results within a few seconds.
Differences are clearly and precisely documented in the proof report, for optimal communication and archiving.
Proofreading with diligence and with constant attention, even for completely changed layouts.
No training required. Instantly use PDiff productively.
With PDiff you see the differences at a glance. You can focus on what matters most: examining and reviewing your texts.
How to compare PDF files with PDiff.
Drag two PDFs into the PDiff window and you will see all text differences in the unique synchronous display. Proofreading becomes seeing instead of searching.
PDiff finds the differences.
This works even if the fonts, layout, hyphenation or even page breaks have been changed.
Interactive instant comparison.
PDiff allows the interactive comparison of PDFs directly on the screen. Hover the cursor over a word and see the corresponding passages highlighted in both documents.
Need proof of matches or the exact changes made? The reports document the results however you like.
Checking foreign-language texts.
PDiff comes with full Unicode support. You can also easily compare texts in non-Roman writing systems.
Support for DOC, RTF, TXT, and more.
PDiff provides an import mechanism for all common document formats. Formats other than PDF are converted automatically by calling their native applications.
Just right for your documents.
PDiff is an ideal solution to compare versions of your documents:
- important office documents
- mission critical technical manuals
- legal texts and business contracts
- financial reports
- manuscripts and thesis texts
- scientific articles, reports, and proceedings
- fictional books and non-fiction books
- copywriting to ready-to-print layout
Comparing apples and oranges? No problem!
With PDiff you can also compare documents where the layout differs widely: for example, check the print-ready layout against the copy text.
Special functions for packaging.
PDiff Professional also supports the comparison of rearranged texts. So you can check even complicated layouts of packaging against the original text. For example you can compare copy text with the text of a press-ready folding box that does not even have a defined text flow direction.
Did you know…
…that the English idiom to compare apples and oranges, as depicted in the PDiff icon, translates differently to other languages. Another common idiom - e.g. in French, German, Spanish, and Italian - uses the expression apples and pears to describe the comparison between dissimilar things.
