Microsoft PowerPoint's Built-in Compare Feature
Microsoft PowerPoint has a "Compare" feature that can help you identify differences.
- Open one of the two PPTX files you want to compare. It doesn't matter which one, but typically you'd open your "original" or "base" version.
- Go to the "Review" tab on the PowerPoint ribbon.
- In the "Compare" group, click on "Compare".
- A dialog box will open. Navigate to and select the second PPTX file you want to compare to the currently open one.
- Click "Merge".
What happens next:
- PowerPoint will merge the selected presentation with the one you had open and display the merged file in "Review mode."
- A "Revisions" pane will appear on the right side of your screen. This pane lists all the changes made to the presentation, categorized into "Slide changes" (changes on the current slide) and "Presentation changes" (changes affecting the whole presentation, like added/deleted slides).
- You'll also see annotations on the slides themselves highlighting specific changes (e.g., text edits, object movements, image changes).
- You can then review each change, click on the highlighted areas, and choose to accept or reject them individually.
- Once you've finished reviewing, click "End Review" on the Review tab and save your changes.
