Convert Images for Laser Engraving

Laser engraving and cutting machines require vector files with precise paths. Vectorr converts your images to SVG, DXF, or G-code optimized for laser software like Lightburn, RDWorks, and LaserGRBL.

Why Vectorr for Laser Work?

Precise Paths: Laser engravers follow vector paths exactly. Our AI generates smooth, accurate curves with minimal node count for fast, clean cuts.

No Overlapping Lines: Overlapping paths waste time and burn material. Vectorr automatically removes duplicate paths and simplifies geometry.

Multiple Formats: Export to SVG (most common), DXF (CAD-compatible), or G-code (direct machine control).

Laser Cutting vs. Engraving

Cutting: Full-power laser passes that cut through material. Use outline paths only (no fills). Export as DXF or SVG with stroke-only paths.

Engraving: Lower-power laser that etches the surface. Can use filled paths or raster images. Export as SVG with fills, or use bitmap engraving mode in your laser software.

Scoring: Medium-power passes that mark but don't cut through. Use thin stroke paths (0.1mm or less). Export as SVG or DXF.

Workflow for Lightburn

  1. Upload your image to Vectorr.
  2. Adjust detail: For cutting, use lower detail to get clean, simple outlines. For engraving, higher detail preserves texture and shading.
  3. Export as SVG or DXF.
  4. Import to Lightburn: File → Import → select your file.
  5. Assign layers: In Lightburn, assign cut power, speed, and number of passes to each layer.
  6. Frame and cut: Use Lightburn's frame tool to preview the cut area, then run the job.

From Raster to Toolpath

A laser does not read SVG directly. The chain is image to vector to toolpath: the vector defines where the head travels, and the G-code or LightBurn file assigns power and speed to each move. Mistakes in the vector stage are permanent, because the laser cannot smooth a jagged path after the fact — it simply follows it.

Two vector properties matter more than any other at this stage. First, closed contours: an unfilled outline still engraves, but a contour that does not close leaves a tiny gap in the final shape. Second, minimal overlapping nodes: a path that doubles back on itself burns twice at the same spot, producing a dark line where the artwork shows none.

Engrave Versus Cut

Engraving uses fill; cutting uses stroke. A conversion that preserves color fills gives you a raster-style engraving where every region is burned at the preset power. A conversion that emits outlines gives you a cutting file. Decide which you want before converting, because the two need different trace settings — engraving keeps detail, cutting needs simplicity.

Why DXF Beats SVG for Some Machines

Older controllers and RDWorks-based cutters handle DXF more reliably than SVG. DXF carries geometry with explicit layer names and no CSS, so there is nothing for the controller to misinterpret. If a machine ignores fills or collapses layers, converting to DXF and reimporting often fixes it without changing the artwork.

Material Notes

Engraved fill density changes how dark the result looks, not just how deep. Too dense a fill pattern over a large area heats the material unevenly and warps thin stock. For a large filled region, reduce fill density rather than power, which keeps the depth consistent across the shape. Always run a small test cut on scrap before committing a full sheet — power scales with material, not with the design.

Frequently Asked Questions

Does a laser cutter read SVG directly?

Not usually. The design is converted to a toolpath in software such as LightBurn, which then drives the machine. SVG is the vector source, not the file the laser runs.

Should I convert for engraving or for cutting?

Engraving uses filled regions and keeps detail; cutting uses outlines and needs simple closed contours. Choose before converting because the settings differ.

Why use DXF instead of SVG for a laser?

DXF carries geometry and layer names with no CSS, so older and RDWorks-based controllers interpret it more predictably than SVG.

How do I stop a large filled area from warping?

Reduce fill density rather than power. Lower density keeps heat spread even and preserves consistent depth across the shape.
