Supports PNG, JPG, BMP, WEBP up to 5MB
Importing SVG into LightBurn
File > Import → select your SVG. Or drag and drop directly onto the LightBurn workspace.
- File > Import (or Ctrl+I)
- Drag SVG file onto the LightBurn workspace
- LightBurn imports all SVG paths and assigns colors automatically
- Grouped paths import as groups — click to ungroup if needed
SVG Color Layers in LightBurn
LightBurn uses SVG path colors to assign operations. Each unique color in the SVG creates a separate layer in the Cuts/Layers panel.
| SVG Color | Suggested Operation |
|---|---|
| Black (#000000) | Cut (full power, slow speed) |
| Red (#FF0000) | High-power engrave |
| Blue (#0000FF) | Low-power engrave / mark |
| Green (#00FF00) | Score / perforate |
Configuring Cut Settings
In the Cuts/Layers panel, click each color layer to configure its operation.
- Select layer in Cuts/Layers panel
- Choose operation: Line (cut/score), Fill (engrave), or Offset Fill
- Set Speed (mm/s) and Power (%)
- Test with 'Send' on scrap material before final cuts
- Use Material Test (File > Material Test) to find optimal settings for your material
Preparing SVG for LightBurn
The better your SVG, the better your cuts.
- Use closed paths for clean cuts (open paths cause incomplete cuts)
- Simplify paths to reduce node count — fewer nodes = smoother machine movement
- Group related elements before importing for easier layer management
- Set document units to mm in your SVG editor to match LightBurn's coordinate system
- Test import with a simple shape before importing complex designs
Frequently Asked Questions
What laser machines work with LightBurn?
LightBurn supports most diode lasers (xTool, ORTUR, sculpfun) and CO2 lasers (Ruida, GRBL, Marlin). Check lightburnsoftware.com for the full compatibility list.
Can LightBurn directly import PNG or JPG?
Yes. For engraving (raster burns), LightBurn imports PNG/JPG. For vector cutting, use SVG or DXF.
Why do my SVG cuts have small burns at path start/end points?
Increase overscan setting and adjust lead-in/lead-out to move the laser's acceleration/deceleration zone away from the design. Also try 'Smooth Corners' in Cut Settings.
How do I convert a PNG logo to SVG for LightBurn cutting?
Use our free converter: upload the PNG, download SVG. Import into LightBurn. Simplify paths in Inkscape first for cleaner cuts.
What SVG features does LightBurn not support?
LightBurn ignores SVG fills (it only follows paths for cutting). Gradients, patterns, and embedded raster images in SVG are ignored. Create path-only SVGs for cutting.
