PNG for LightBurn Engraving
LightBurn is the leading laser control software for diode and CO2 machines including xTool, Sculpfun, Atomstack, Ortur, and Ruida-based systems. LightBurn treats PNG images and SVG vectors as separate layer types — understanding this determines whether your artwork engraves as a filled image or as crisp vector outlines.
About PNG for LightBurn engraving
LightBurn handles PNG images and SVG/DXF vectors differently. Understanding this distinction determines whether a logo engraves correctly or produces an unexpected result.
LightBurn PNG vs SVG — the key difference: - PNG imported into LightBurn becomes a raster engrave layer: the laser scans horizontal lines, burning darkness relative to each pixel's greyscale brightness. - SVG/DXF paths in LightBurn become vector layers: the laser follows each path exactly — ideal for outline engraving and cutting. - For logo fills and photographic engravings: a high-contrast PNG at 500–1000 DPI produces excellent detail. - For crisp outlines and cut contours: SVG vector paths give the cleanest results.
How to prepare files for LightBurn engraving: 1. Upload the logo or artwork to the PNG-to-SVG converter above. 2. Download the SVG for outline and cut paths. 3. In LightBurn: File > Import > select the SVG. Assign to a Line or Fill layer with appropriate speed and power settings. 4. For a raster fill engrave: import the original high-contrast PNG directly. Set mode to Fill (scan), DPI to 254 or 508. 5. Combine both layers for mixed results — filled image engrave plus a cut outline.
LightBurn settings for logo engraving on wood (20W diode laser): - Fill layer: 60–80% power, 4000 mm/min, 254 DPI - Line layer (outline): 90% power, 600 mm/min
