Sometimes, you’ll want to apply a new theme to an existing presentation to change its design.
- To apply a new theme, click Slide at the top, then select Change theme. Click on a theme to see how your presentation will look.
- To use a different theme from the ones offered by default, click Import theme at the bottom. Then choose a presentation from Google Drive or upload one from your computer.
- All your slides will adopt the new look and formatting prescribed by the theme.
