How to compare pdfs

  1. 1

    Drop the original PDF on the left and the revised PDF on the right.

  2. 2

    The tool compares every page's text and a low-resolution render of both versions.

  3. 3

    Browse the page-status overview and jump straight to the pages that changed.

  4. 4

    Review word-level changes — removed text in red, added text in green — under the side-by-side view.
