Convert PNG to SVG for Laser Cutting
PNG raster files must be converted to SVG before they can be used for laser cutting. Laser controllers follow vector paths for cut operations — a PNG has no path data and is only usable for laser engraving in bitmap scan mode.

No account is required to create or view the protected preview. The preview accepts one PNG, JPEG, or WebP file up to 4 MiB; other source formats must be exported or converted to one of those formats first. Editable SVG export requires paid or complimentary access. Review the exported SVG in the appropriate downstream software; non-SVG formats and machine instructions require separate conversion.

PNG limitations for laser cutting: - Bitmap engraving: PNG files can be used for laser engraving (scan mode), where the laser passes over each row of pixels. This produces engraved fills but not cut outlines. - No cut paths: to laser-cut a shape, a closed vector path is required. PNG files cannot provide this. - Resolution limits: PNG files pixelate when scaled up; SVG paths remain clean at any size.
PNG to SVG for laser cutting — step by step: 1. Upload the PNG to the vectorizer above. 2. For a cut file, ensure the design is high-contrast with a clear boundary. Black-on-white works best. 3. Import into LightBurn and assign to the Line (cut) layer. 4. Verify all paths are closed — use Edit > Close Open Paths in LightBurn. 5. Run a frame test before cutting to confirm dimensions and position.
File format notes: - LightBurn imports SVG, DXF, and AI files for cutting operations. - SVG is the most universally compatible format for laser software. - DXF is preferred for CNC routers and plasma tables. - For Glowforge, SVG files are the native import format.
Best practices: - Black-on-transparent PNG converts to a single clean path in the SVG. - Avoid very thin lines under 0.5 mm — they may not cut completely on lower-power lasers.
