PowerPoint Online doesn't have the ability to make a picture transparent. Use the desktop PowerPoint app if you want to make a background picture transparent.

Remove a background

If you have just added a background picture or color and decided not to use it, you can remove it by using Undo Undo your last action on the Home tab of the ribbon.

If the Undo command doesn't work, you can remove whatever slide background you currently have by resetting to a solid white background:

  1. On the Design tab, tap or click Format Background.

  2. Tap or click Solid Fill, and pick White, Background 1 at the top left corner of the color picker.
