Question details
Users need a way to adjust the font size of SmartArt objects generated by Designer when using the web version of PowerPoint.

- Product
- PowerPoint for the Web
- Device & OS
- Mac
- Scenario
- Editing presentations online and attempting to format SmartArt graphics created by the PowerPoint Designer feature.
- Observed behavior
- The font-size controls are disabled or unavailable for SmartArt objects within the web application interface.
Ensure you have access to a desktop presentation application, as this formatting limitation is specific to the web browser version of PowerPoint.
Edit SmartArt using Desktop Presentation Software
Since PowerPoint for the Web restricts this formatting feature, downloading your file and opening it in a desktop application is the most effective solution.
The web version of PowerPoint lacks full support for editing complex Designer objects. Transitioning to a desktop environment bypasses this restriction entirely.
In PowerPoint for the Web, navigate to File > Save As and select 'Download a Copy' to save the .pptx file to your computer.
Locate the downloaded .pptx file and open it using your desktop PowerPoint application or a compatible alternative like WPS Office.
Click on the SmartArt graphic, highlight the specific text you wish to change, and use the font size dropdown menu in the Home tab to make your adjustments.
Press Ctrl+S (or Cmd+S on Mac) to save your changes, then upload the file back to your cloud storage if you need to continue sharing it online.

Submit Feedback to the Microsoft 365 Team
If you rely heavily on the web version, reporting the issue helps prioritize future updates to PowerPoint for the Web.
Edit SmartArt and Presentations Seamlessly with WPS Office
Avoid web-based formatting limitations by using WPS Office. It provides full editing capabilities for presentation graphics on your desktop, without the restrictions found in many browser-based tools.
- 1. Open your file in WPS Presentation: Launch WPS Office and open your downloaded .pptx file directly to begin editing.
- 2. Select the SmartArt object: Click directly on the SmartArt graphic or Designer object that you could not edit on the web.
- 3. Modify text formatting: Use the comprehensive formatting tools in the Home tab to adjust font sizes, colors, and styles without any restrictions.
