Step 2: Inside, open the two PDF files you want to compare. You can do that by clicking on Select File for each side, or simply dragging them into the window.

Step 3: And that’s it. Adobe will automatically highlight changes between the two PDF files.

Additionally, it will also create a report on the outcome for your perusal.
