It allows users to select specific parts of the image based on color similarity. One of the easiest ways to get rid of a background on GIMP is by using the Fuzzy Select tool. Some are perfect for beginners, whereas others are aimed at more experienced GIMP users. When creating a transparent background, a few tools can be applied depending on the edited image. Lower the newly created layer.Available on both Mac and Windows, GIMP is a great, free alternative to Adobe Photoshop with many of the same features available.
