Convert PNG to SVG for CNC
CNC machines require vector path data to define toolpaths. Converting PNG to SVG creates the closed vector outlines that CNC routers, laser cutters, plasma cutters, and vinyl plotters follow during operation.
About Convert PNG to SVG for CNC
CNC routers, laser cutters, plasma cutters, and vinyl cutters all require vector SVG (or DXF derived from SVG) to define toolpaths. PNG is a raster format with no path data — the conversion to SVG creates the vector outlines that CNC software reads as cut or engrave paths.
Converting PNG to SVG for CNC: upload the PNG to the vectorizer. The vectorizer traces the image outlines and colour regions into clean SVG paths with defined closed shapes. Download the SVG and import it directly into your CNC software or use it as the source for DXF export.
CNC software that accepts SVG directly: LightBurn (laser cutters), Easel (X-Carve CNC), Carbide Create, Vectric VCarve, Fusion 360, Inkscape (for further DXF export), and most vinyl cutter software (Silhouette Studio, Roland Cut Studio) all import SVG natively.
Preparing SVG for specific CNC operations: for routing and cutting, paths should be single closed outlines. Filled shapes define the area to be cut away or the boundary of the part. For engraving, filled shapes define engraving areas. For laser cutting, use separate SVG layers and colours per operation (cut vs. engrave) for clean layer control in LightBurn or similar software.
After converting, simplify the SVG paths to reduce node count — fewer nodes produce smoother toolpaths and faster CNC operation. Use Inkscape's Path > Simplify before importing into CNC software.
