Questions

How does the comparison work?

Each page of both files is drawn and compared pixel by pixel. Changed areas are shown in red.

Is it safe to compare PDFs here?

Yes. Your PDF is processed inside your browser and is never uploaded. We never see, store or own your files, and the tool works even offline once the page has loaded.
