Advice
- Using a JPEG image file instead of other image formats will help reduce the overall size of the presentation.
- When formatting a slide show, using a default minimalist background image in a slide will make your file smaller than uploading detailed backgrounds.
- If you can’t make the PowerPoint file small enough to email it, you can upload the file to a cloud service (such as Google Drive) and email it with a link to the file instead. Recipients will be able to download files from Google Drive.
Warning
- Reducing the image quality will make a significant change in the overall quality of the PowerPoint presentation.
