Use Case
For laser-cutter and CNC hobbyists and makerspace users who need to turn a raster image into smooth vector outlines that LightBurn, Glowforge, or xTool can cut or engrave.
Privacy
Laser cutters follow vector paths — the cleaner the contour, the cleaner the cut or engrave — so a raster image must be traced into smooth SVG outlines first. This tool does it locally in your browser with no upload, so your project files stay yours. For laser work we default to a very low numColors of 4, because a laser typically cuts or engraves distinct regions, not photographic gradients; collapsing the image to a few tones gives you crisp, well-defined boundaries the machine can follow. We use a higher pathomit to eliminate noise specks that would otherwise become tiny wasteful laser moves, and we keep ltres and qtres tight so curves stay smooth rather than faceted — important when the beam traces every wobble. Turn on Cartoon Mode to flatten a busy photo into bold shapes ideal for engraving, or drop numColors to 2 for pure cut-line silhouettes. Import the SVG straight into LightBurn or your Glowforge or xTool workflow, assign cut versus engrave layers by color, and run the job.
