SVG vs DXF for Laser Cutting — Choosing the Right File Format
SVG and DXF are both vector formats used for laser cutting — compare which format your laser cutter software accepts and which produces cleaner cuts.
Which Format to Use for Which Laser Cutter
Most diode laser cutters (xTool, Sculpfun, Ortur) accept SVG directly. CO2 laser software (LightBurn) accepts both SVG and DXF with equal quality. CNC routers and industrial laser cutters often prefer DXF. Check your specific machine's software before designing.
- xTool, Sculpfun, Ortur: accept SVG directly
- LightBurn (most laser cutters): accepts both SVG and DXF
- Industrial CNC, AutoCAD-based machines: prefer DXF
Technical Differences for Laser Cutting
SVG supports fill colors (used for raster engraving areas) and stroke (used for cut paths). DXF is a CAD format that handles cut paths well but has less standardized color/layer support across different software. For Cricut: SVG only. For laser cutting: SVG or DXF depending on your machine.
- SVG: fill for engraving areas, stroke for cut lines
- DXF: CAD standard, preferred by AutoCAD/Fusion 360 users
- LightBurn: import both, define colors as cut/engrave/score layers
Frequently Asked Questions
Can I use SVG files with a CO2 laser cutter?
Yes — most CO2 laser cutters running LightBurn software accept SVG directly. SVG colors map to LightBurn layers for cut/engrave/score operations. Test a small area before cutting a full design.
How do I convert SVG to DXF for laser cutting?
Open the SVG in Inkscape and export as DXF via File > Save As > Desktop Cutting Plotter (AutoCAD DXF). Or use an online SVG-to-DXF converter. Test the DXF in your laser software to ensure paths imported correctly.
