To compare sessions visually side by side

Comparing two versions of your PDF document visually is useful to see visible changes “at a glance”. The idea is that you select two sessions and click the Compare Visually button. PitStop Pro will then generate two snapshots showing the state of the PDF document at the end of the respective sessions and present these snapshots side by side on screen.


  1. Choose Certified PDF > Show History.
  2. Select two sessions from the session list.

    The Visually (side-by-side) button is enabled.

  3. Click Visually (side-by-side).

    PitStop Pro compares the two versions and displays them next to each other on screen, indicating the differences.
