Introduction

Before presenting your PowerPoint, you might decide to ask someone else to look over it. The two of you might even collaborate on a presentation. If you were revising a hard copy of a report, you might add comments in the margins or compare your rough and final drafts side by side. You can also do these things in PowerPoint using the Comments and Compare features

Comparing presentations

If you are collaborating on a presentation or asking someone else to review your presentation, you might want to use the Compare feature. The Compare feature combines two versions of the same presentation. This allows you to see the differences between the two and decide which changes to include in the final version of your presentation.

To compare two presentations:

Before you start, you'll need to have one version of the presentation open. When you're ready to compare, you'll select the second version.

1. Select the Review tab, then locate the Compare group.
