What is Compare PDF?

Comparing PDFs shows the differences between two versions of a document, such as a contract before and after edits, so nothing changes without you noticing. SuperPrompts' free Compare PDF tool extracts the text of both files and lines them up page by page, highlighting text that was removed from the first version and text that was added in the second. It also reports when the page counts differ. This makes it quick to review redlines, check that only agreed changes were made to an agreement, or spot edits in a policy, quote or manuscript. Compare PDF checks text content, not visual layout, so changes to images or formatting alone are not flagged.
