Compare a revised PDF to an earlier version

The Document Compare feature lets you see the differences in two versions of a PDF, as well as select the type of differences you’re looking for to verify that the appropriate changes have been made. The Document Compare feature does not compare comments in the PDF.

  1. Choose Advanced > Compare Documents.
  2. Specify the two documents to be compared. If necessary, click Choose, select the file, and then click Open. If the documents are open, you can select them from a menu.
  3. Under Type Of Comparison, select one of the following:
    Option Description
    Page By Page Visual Differences

    Finds any textual or graphic differences between the documents. Select the level of detail you want from the menu.
    Textual Differences

    Shows which text has been inserted, deleted, or moved.
    Include Font Information

    Compares formatting.
  4. Under Choose Compare Report Type, select one of the following:
    Option Description
    Side By Side Report

    Creates a new PDF that displays the two documents in Continuous-Facing mode.
    Consolidated Report

    Adds markups where the differences occur in the current document. When you hold the pointer over a markup in a consolidated report using the Hand tool, the differences appear.
To compare text-based documents, you may want to select Textual Differences to appear in Side By Side Report format. For technical drawings, you may want to select Page By Page Visual Differences to appear in Consolidated Report format.
