SVG vs DXF for Laser Cutting — Format Comparison
SVG and DXF are both vector formats used for laser cutting. Learn which format your laser software prefers, when each is more accurate, and how to convert between them.
SVG for Laser Cutting
SVG is natively supported by Glowforge, LightBurn, and most modern laser software. SVG handles color-coded operation layers, allows both raster engrave and vector cut in one file, and is web-friendly for sharing files.
- Glowforge: SVG is the primary supported format
- LightBurn: SVG import is accurate and color-layer aware
- SVG supports: fills (engrave), strokes (cut/score), embedded rasters
- File compatibility: opens in Inkscape, Illustrator, browsers
DXF for Laser Cutting
DXF (Drawing Exchange Format) comes from CAD software and is preferred by many CNC and precision laser cutters. It stores exact coordinates with higher numerical precision than typical SVG exports. No fill/color support — cut lines only.
- K40 and CO2 lasers: often prefer DXF over SVG
- CAD-based laser software: native DXF support
- DXF: precision coordinate data, no color layers
- DXF: cut outlines only — no fill engrave support in this format
- Better for: mechanical parts, precision cutting, CNC routing
Frequently Asked Questions
Should I use SVG or DXF for Glowforge?
SVG — Glowforge's primary format. DXF is not natively supported by Glowforge.
Should I use SVG or DXF for xTool with LightBurn?
LightBurn accepts both SVG and DXF. SVG is preferred when you need color-coded layers. DXF is useful for importing from CAD software.
How do I convert SVG to DXF for a CNC laser?
In Inkscape: File > Save As > Desktop Cutting Plotter (.dxf). Or use imagetosvg.com's DXF export option. In LightBurn: open SVG, then save as DXF.
Which format is more accurate — SVG or DXF?
DXF typically stores higher coordinate precision (more decimal places). For most craft laser cutting, SVG precision is fully adequate.
