Hey PhotoEnthusiast123,
I highly recommend remove background (https://www.perfectcorp.com/consumer/blog/photo-editing/how-to-remove-background-from-picture). It's an online tool that's incredibly easy to use. Just upload your image, and it automatically removes the background in seconds. It's perfect for quick edits, and the results are usually very accurate. They offer a free tier, although you might be limited in terms of resolution.
Great for casual use!
