The checkerboard shows transparency. In Chroma key mode, click a background pixel to erase every pixel near that color. In Flood fill mode, each click erases one connected region.

Higher tolerance removes more. Feather fades the cut edge over a soft band instead of a hard silhouette. Click any pixel in the preview to key that color, or use the picker.
Click a pixel in the preview to erase its connected color region (repeated clicks peel more layers). Feather smooths the new cut edge; previous cuts stay crisp.
Chroma mode re-applies live as you move the sliders. Flood mode only affects your next click. Undo walks back up to the last 12 edits.
Export
Load an image first. PNG keeps full transparency; the JPG variant flattens it onto white for use in docs and slides.
