Convert SVG to Laser Cut File
An SVG file is already vector — it just needs to be structured correctly for laser cutting. This guide covers how to prepare any SVG for import into LightBurn, LaserGRBL, and other laser cutting software for cut, score, and engrave operations.
About Convert SVG to laser cut file
Laser cutting software reads SVG files directly — no format conversion is needed. But not every SVG is immediately usable as a laser cut file. SVG structure, colour coding, and path type determine how the laser software interprets each element.
Key SVG requirements for laser cutting: — Cut paths: stroked paths (no fill) with a designated cut colour (commonly red #FF0000). The laser follows this path at full power. — Score/fold lines: stroked paths at reduced power — use a different colour (commonly blue #0000FF) or a separate layer. — Engrave regions: filled areas with no stroke, or hatched fills. The laser engraves the area at configured scan speed and power. — Hairline strokes: set stroke width to 0.001in or 0.025mm to signal a path (not an area fill) to the laser software.
Preparing SVG for LightBurn import: 1. Assign unique fill or stroke colours per operation type. 2. Group elements by operation on separate layers or colour codes. 3. File > Import in LightBurn — each colour maps to a LightBurn layer. 4. Assign cut speed and power per layer from LightBurn's Cuts/Layers panel. 5. Preview and confirm path directions before cutting.
If the SVG came from a raster trace, run Path > Simplify in Inkscape before importing. Overly complex paths cause slow engraving and jagged cut edges.
