Quickly remove multiple slide masters in PowerPoint and any unused slide masters, to reduce PowerPoint Presentation file size.

Marketing teams often create PowerPoint Presentation Templates with a large number of Slide Masters to ensure brand compliance for every variation of slide layout. These PowerPoint slide masters in the template become part of each PowerPoint presentation file that is created using the template. As a result, they can cause the PowerPoint presentation file sizes to be unnecessarily large.

In addition, whenever you paste a PowerPoint slide into a presentation from another template, PowerPoint adds the Slide Masters from the original template to your current Presentation - which results in multiple PowerPoint slide masters.

Once you finish creating a PowerPoint presentation, you can reduce the file size by deleting unused Slide Masters, but it can be a time-consuming task to identify each layout that is unused.

To solve this problem - PPT Productivity's Proofing tools has a Slide Masters Review feature. This feature checks your PowerPoint presentation and identifies multiple slide masters and unused slide masters. You can then choose to retain or delete the extra slide masters.

Removing multiple slide masters in PowerPoint is the best way to reduce your file size without needing to change your actual presentation content.
