To remove the background from your photo, use the Background Remover tool. First, select the area of the photo you want to keep, and the tool will automatically identify the background and remove it. You can refine the selection using the Refine or Restore tool, and adjust the sensitivity of the tool to get the best results. Once you have removed the background, you can replace it with a new background image using the Add Image tool, or with a solid color using the Background Color tool.
