- Scenario
- Downloading a PowerPoint presentation from the web application to use locally from a USB drive.

Download the File Locally and Remove Problematic Fonts
Use this solution to bypass web-app font limitations by downloading the file and replacing the unsupported embedded fonts using a desktop application.
Font embedding is heavily restricted in PowerPoint for the web, macOS, iOS, and Android. Only certain Windows desktop versions of Office fully support it. To fix file opening errors, you must first save a local copy of the file and replace any restricted fonts.
Log into your OneDrive or the PowerPoint web application. Select your presentation, choose 'File' or click the context menu, and select 'Download a Copy' to save the file to your computer's local drive.
Launch the desktop version of Microsoft PowerPoint on your Windows computer and open the downloaded presentation file.
Navigate to the 'Home' tab on the ribbon, click the drop-down arrow next to 'Replace', and select 'Replace Fonts'. Choose the problematic embedded font from the list and replace it with a standard system font like Arial or Calibri.
Go to 'File' > 'Save As' and select your connected USB drive. Before saving, click 'Tools' > 'Save Options' and ensure the 'Embed fonts in the file' checkbox is unchecked. Click 'Save'.

Repair Corrupted Presentation Files
If the presentation continues to throw errors after downloading from the web, use the built-in repair tool to fix internal corruption.

Frequently Asked Questions
Why do embedded fonts cause my PowerPoint presentation to fail?
Font embedding is highly restricted by licensing and platform compatibility. Fonts embedded in Windows desktop versions may not render or open properly on macOS, mobile devices, or PowerPoint for the Web, often resulting in file corruption errors when transferred.
Can I embed fonts using PowerPoint for the Web?
No, font embedding is not supported in PowerPoint for the Web. You can only embed fonts using specific Windows desktop versions of the Microsoft Office suite.
How do I safely transfer a web presentation to my USB drive?
To transfer a presentation from the web, first download a copy of the file from OneDrive or the web app to your computer's local hard drive. Once downloaded, navigate to the file, copy it, and paste it into your connected USB drive folder.
What should I do if my downloaded presentation is corrupted?
If the downloaded file will not open, launch your desktop version of PowerPoint and use the 'Open and Repair' option from the 'File > Open' dialog box. Alternatively, you may need to replace the problematic embedded fonts in a working copy before downloading.
