Microsoft PowerPoint relies heavily on fonts to display presentations correctly. However, users may encounter issues where fonts are missing, substituted, or appear corrupted when opening a presentation. This can disrupt formatting, change layouts, and affect the overall look of your slides.
These issues typically occur when the required fonts are not installed on your system, the presentation uses custom fonts, or font files become corrupted. In some cases, compatibility issues between different devices or PowerPoint versions can also cause font-related problems.
In this guide, we’ll walk you through effective methods to fix missing or corrupted fonts in PowerPoint on Windows 11.
