SVG for Laser Cutting: Glowforge, xTool & Cricut File Guide

How a laser cutter reads an SVG

Unlike a printer, a laser follows the outline of each vector path. A well-formed SVG for laser cutting is plain XML with styles inline and no external CSS references, because most laser software ignores or mangles external stylesheets.

Machines assign operations by stroke color and fill. On Glowforge the convention is red stroke = cut, blue stroke = score, and black fill = engrave. xTool's XCS software instead groups operations by SVG layer, so naming layers Cut, Score, and Engrave gives the smoothest import. Cricut Design Space treats the whole SVG as cut lines, so keep it to clean silhouettes.

Convert your image to a laser-ready SVG

Start from the highest-contrast source you have. A dark design on a white or transparent background traces into far cleaner paths than a busy photo. Remove the background before converting so you do not get a stray rectangle around the whole design.

Upload the image to the converter, use the Logo or Clean preset to keep the path count low, and reduce the color count. Fewer colors means fewer separate paths for the laser to process, which is exactly what you want for cutting and engraving.

Set strokes and fills for cut, score, and engrave

For cut lines, give the path a thin hairline stroke and no fill — a filled shape will be engraved solid instead of cut around. For engraving, use a solid fill and no stroke. For scoring (a shallow crease rather than a full cut), use the score color your machine expects.

After converting, open the SVG in a free editor like Inkscape to recolor strokes to your machine's convention and confirm each element is on the right operation before sending it to the laser.

Clean up paths to avoid doubled or failed cuts

The most common laser problem is a doubled cut, where two overlapping paths sit on the same line and the laser burns it twice. Auto-traced SVGs sometimes create both an outer and inner path around a stroke, so simplify paths and merge duplicates before cutting.

Also make sure cut paths are closed. An open path can leave your piece attached to the sheet or produce an incomplete outline. A quick check in your laser software's preview or Inkscape's node editor catches this before you waste material.

Tips and best practices

• Test on scrap material first — stroke-color conventions differ slightly between Glowforge, xTool, and Cricut.
• Keep engrave areas as solid fills and cut lines as hairline strokes; never rely on stroke width to define a cut.
• Use a transparent-background SVG so no bounding rectangle gets cut around your design.

Common mistakes to avoid

• Leaving a white background in the SVG, which becomes an extra cut or engrave shape.
• Using thick strokes for cut lines, which some software engraves instead of cutting.
• Sending overlapping duplicate paths that cause the laser to cut the same line twice.

Conclusion

A laser-ready SVG is less about how the design looks and more about how its paths and colors are structured. Get the stroke colors, fills, and path cleanup right and almost any image can become a reliable cut file.

Convert to SVG first, assign cut, score, and engrave, then verify closed, non-duplicated paths before you send the job.
