Compare two PDFs to quickly view changes.

Spot changes fast with a visual comparison.

PDF comparison is easy with Adobe Acrobat. The Compare Files tool helps you quickly and accurately detect differences between two versions of a PDF. You can compare documents in a side-by-side view or choose single page view to review all changes in your latest PDF document. It lets you quickly compare text, images and graphics so you know exactly what has been changed from a previous version. With the handy highlight bar, each change is conveniently called out for you in the new document.

Get a summary report of changes.

Our comparison tool automatically creates a document comparison results summary to show you how many changes were made to the original document. The summary shows you how many things were replaced, inserted or deleted. Then, you can peruse the PDF to see the changes in context. It’s a quick way to see how much has changed.
