Compare Presentations Manually in PowerPoint 2016 for Windows

While PowerPoint does have an option to automatically compare presentations, you might want to consider doing this comparison manually. This approach can be more effective, especially when you have fewer slides to compare in the first place. You can place both presentations side-by-side and compare individual slides.

Follow these steps to manually compare two presentations in PowerPoint 2016 for Windows:

1. Ensure that only the two presentations you want to use for comparison are open. Close any other open presentations.
2. Access the View tab of the Ribbon and click the Arrange All button, as shown highlighted in red within Figure 1, below.
3.

3. Doing so will arrange both presentations in different windows side by side, as shown in Figure 2, below. You can now compare individual slides on both presentations with each other.
4.

4. If you find some slides are missing in one of the presentations, you can copy slides between two presentations. To do so, you can change the view on both open presentations to Slide Sorter view, as shown in Figure 3, below.

5. Next, drag and drop any slides, as needed, from one presentation to the other to copy slides.
6. Save your presentation often.
