Google has announced that Google Workspace for Education domains can now allow users to replace their backgrounds with an image in Google Meet. You can either use Google’s pre-set images or upload your own image. Currently, custom backgrounds can only be set when in a Google Meet session within Google Chrome on Chrome OS, macOS, and Windows devices. Support on the Meet mobile apps will be coming soon.
Visit the Google Help Center to learn more about how to change your background in Google Meet.
This feature should have begun to show up in U-M Google on February 2, 2021, but it could take a day or two to become fully visible.
