How to Compare PDF Files

In any single project, many changes can be made to a single document at any given point, and it follows that many copies and different versions of that file are saved. When reviewing a document, it is often a tedious task to go back and look at previous versions for missed material or for PDF comparison to find the best PDF version.

Instead of manually searching for previous files in your computer or in your e-mails, Adobe Acrobat 11 Pro offers a simple way to compare and review PDF material in different files. It will let you specify what type of documents you would like to compare as well as the exact page range, and you can also easily keep track of your activities by managing your results and settings in the Compare Navigation pane.


In Adobe Acrobat 11 Pro:

  • 1Go to View > Tools > Document Processing.
Acrobat Document Processing Option
  • 2From the Tools Pane, select Compare Documents.
