How do I change background color of image easily?

Using PowerPoint to change the background color of an image on Windows is a quick and easy option, especially if you don't want to use dedicated image editing software. Here's how you can do it:

Steps to Change Background Color of Image in PowerPoint:

1. Insert your image into PowerPoint:

    Open PowerPoint and create a new slide.
    Go to Insert > Pictures and select your image.

2. Remove the existing background:

    Select the image.
    Go to Picture Format tab.
    Click Remove Background (it may be on the far left).
    PowerPoint will automatically try to identify the background. Use the Mark Areas to Keep and Mark Areas      to Remove tools to refine the selection if needed.
    When satisfied, click Keep Changes.

3. Add a new background color:

    Insert a shape (like a rectangle) that covers the entire slide or just the area behind your image.
    Right-click on the shape, select Send to Back so it appears behind your image.
    Change the shape's fill color to your desired background color via the Shape Fill option.

4. Adjust the image and background:

    Position the image and shape as needed.
    You now have an image with a new background color.

5. Save your image:

    If you want only the image with the new background, right-click the image (or the shape) and select Save      as Picture.
    Save it in your preferred format (PNG recommended for transparency, but since you added a background,      JPEG also works).
