Why compare PDFs in your browser?
Comparing contract drafts or revised reports means handling both versions at once. Doing it locally keeps both documents on your device instead of uploading them to a comparison service.
Frequently asked questions
Are my files uploaded?+

How does it detect changes?+
It renders each page of both files and highlights the pixels that differ, which catches text, layout and image changes.
Can the files have different page counts?+
Yes. Pages that exist in only one file are shown as fully changed.
