Set Your Chrome Avatar
Yes, you can just upload a photo you have. However, if you don’t have a photo you can create an avatar in Google Drawing.
Draw a Circle
Alternatively, if you add a photo to the drawing, you can crop it to a circle! Add the image, click on the image and the cropping tool will appear in the toolbar. Notice the tiny triangle next to the cropping tool. Clicking on the tiny triangle allows you to choose a shape to crop.
Make the Border Thicker
G Suite Avatar
Go to Gmail, Drive, or Classroom to locate your G Suite avatar in the upper right hand corner. Click on this. This will expand out to show you a larger version of your avatar as well as a button to access your Google Account (if you need to change your password.) Click on the larger version of the avatar to change it.
You will then be prompted to upload the avatar you just downloaded from Google Drawing. Drag the download to the upload window. You will need to adjust the cropping so it shows the entire image. Click the blue “Set as profile photo” button and you’re all set!
