Turn a photo or logo into a grayscale heightmap — and one toggle away, a challenge coin.
In Depth mode, click Generate depth map. An AI depth model runs in your browser (free; the first run downloads ~50 MB and caches). The result is a grayscale heightmap where white = highest — exactly what a 3D/relief engrave reads.
Detail comes from your image, not the model. Turn Image detail up (1.5–2) for crisp surface detail, lower 3D form if it looks bulbous, and add a little Sharpen. Use Smooth to remove stair-steps on faces.
Turn on Remove background (AI) to drop the background to a flat base plane, or use Flatten background to push the darkest tones flat. This keeps the relief focused on the subject.
Toggle Challenge coin. Set the diameter (25/40/50/65 mm presets or custom), reposition and zoom the crop, add a raised rim, and type curved top and bottom rim text with a font of your choice.
Export a grayscale PNG. Load it into your laser’s 3D/grayscale mode. If it engraves inside-out, toggle Invert — some machines read white as deepest.
