An AI depth model runs in your browser (free) and turns a photo or logo into a grayscale heightmap: white = highest, for true 3D relief engraving. Turn on “Challenge coin” to frame it as a round coin with a raised rim, adjustable diameter, and curved top/bottom text. Toggle “Remove background (AI)” to isolate the subject. Export a grayscale PNG your laser reads as height.
