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.
Before you start

Ensure you have access to a desktop presentation application, as this formatting limitation is specific to the web browser version of PowerPoint.

Solution 1Recommended

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.

1
Download your presentation

In PowerPoint for the Web, navigate to File > Save As and select 'Download a Copy' to save the .pptx file to your computer.

2
Open in a desktop app

Locate the downloaded .pptx file and open it using your desktop PowerPoint application or a compatible alternative like WPS Office.

3
Adjust the SmartArt font size

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.

4
Save and upload

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.

Edit SmartArt using Desktop Presentation Software
Formatting Retained: Once the font size is changed on the desktop, the new size will be preserved when you view the file again in PowerPoint for the Web.
Free Microsoft Office alternative

Edit SmartArt and Presentations Seamlessly with WPS Office
