Final answer:
To make an image background transparent in PowerPoint, use the Picture Tools Format tab and the Remove Background feature to distinguish the background from the foreground, then adjust the selection and apply the change.
Step-by-step explanation:
To make an image background transparent in PowerPoint, you can use the built-in background removal tool. First, insert the image into your slide. Then, click on the image to select it and go to the Picture Tools Format tab. Within this tab, click on Remove Background. PowerPoint will try to determine the background to remove it, but you might need to adjust the selection by painting over the areas you want to keep or remove.
Once the adjustments are made, press Keep Changes to finalize the transparency. Remember, this feature works best with images having a clear and distinct background.
