PowerPoint slides can contain all kinds of objects, images, and text. It isn't always easy to see if all the different elements in a slide have been edited and what those changes were, specifically. 

compareDocs users told us they wanted to be able to see, at a glance, which slides in their PowerPoint files had changed, and the details of those changes to support a faster review process.

Know if a slide has changed

The default report type is a side-by-side PDF when compareDocs users load in two PowerPoint files. The user can instantly see if there are changes to a slide based on the equal/not equal icon on the page. To narrow it down even further, users can select the Changes Only option to exclude unchanged slides from the report. This report can be opened and viewed as a new PDF, sent as an email attachment, or saved into a document management system. 

Understand the kinds of changes made

The compareDocs PowerPoint comparison report tells the user what changes have been made to a pair of matched slides. The comparison technology behind the report supports the many different objects that can be in a PowerPoint presentation, including speaker notes, shapes, video, and audio. 

The Detail Report adds a table explaining the changes in the slide. It will highlight comments, hidden slides, shape formatting, and more. Users can work down the list and review the changes one by one, or share this report with the author or contributor to show them what's changed.
