About Compare PDF

Contracts come back 'with a few small changes'. Instead of reading forty pages twice, compare the versions: every removed line and every added line is listed per page, with an overall similarity score so you can see how much really changed.

Frequently asked questions

What does it compare?
The text of each page. Layout-only changes (colours, positions) are not reported.
Do the files need the same number of pages?
No. Extra pages are listed as present in only one file.
Does it work on scans?
Only after OCR, since scans have no text to compare.
