With compare mode, it's simple to see exactly what's changed between revisions. Compare mode allows you to compare any two proof versions side-by-sideView and resolve comments to ensure amendments were completed between the versions.If you have more than one version, you'll see the option to Compare Revisions next to the version control menu.For PDF files, as long as pages of both versions is the same,  the pages will remain in sync while you navigate  through each page.To turn off page sync, you can toggle off Sync Panes.While in compare mode, you can review comments and resolve them as well.With Synchronised Zoom and Pan you can quickly see what's changed between any two versions of the proof. Compare feature is currently supported on PDF and image files. We plan to launch support for video files soon.Note: You can only compare versions if they are of the same file type. i.e you cannot compare a PDF with an image file.
