1. Open Paint 3D and click New to create a new document.
  2. Click the folder icon in the upper left corner to bring up the settings menu.
  3. Choose Insert.
  4. Select an image and click Open to place it on the canvas.
  5. Click Magic Select to enable the tool you’ll use to remove the background.
  6. Drag the corners or sides of the image until it removes most of the background while still featuring the subject you’d like to keep.
  7. Click the Next button to remove the background. 8. Use the add and remove buttons at the top to draw on additional areas needing removed (or stuff that needs to be added back), if necessary. Often times, this does the trick, and there’s no additional drawing needed, but some images are complex, and require a little massaging to get a good finished product.
  8. Click the Done button.
