Top Con

Crashes often

Trying to offset one page vs the other causes a crash, etc. See More

Top Pro

GPL license

Could be adopted and improved by anyone. See More

Endolith's Experience

This is the one I've been using. It works pretty well if the originals line up, and with multi-page documents, but crashes often and is abandoned by the developer. See More

Top Con

Offset is very slow

If two pages are offset by a large amount, it will take forever to move them one pixel at a time, since each pixel takes a long time to reload. See More

Top Pro

Supports multiple pages well

Shows all pages in the sidebar, lets you compare them all. See More

Top Con

Unsupported

The main Git page says"this repository is provided as-is and the code is not being actively developed.". See More

Top Pro

Whole-page preview in side panel

If pages from the two documents match, they are shown in green on the left side panel, so you can save time focusing only on the pages that don't match. See More

Top Pro

Graphical red/blue diff

Black lines in the original files are shown as red/blue lines, which become black when they are identical. See More

Adobe Acrobat
