How to Prepare Artwork for a Laser Engraver or CNC Router

Turning a photo or logo into a clean, cut-ready SVG/DXF file.

Laser engravers, CNC routers, and vinyl cutters don't work with photos or PNGs — they follow vector paths, moving the tool head (or beam) along the exact lines a file describes. That's what a DXF file is: a standard vector format built specifically for that kind of machine, and it's usually generated from an SVG that's already been cleaned up for cutting.

What makes artwork "cut-ready"

Clean, closed shapes. A machine needs unambiguous paths to follow — stray pixels, soft anti-aliased edges, or gaps in a line all become problems once they're converted to vector paths a machine has to physically trace.
Enough contrast. Tracing works by finding boundaries between light and dark (or between colors), so a subject with a clear silhouette against its background produces far cleaner paths than a low-contrast image.
The right level of detail. A machine will faithfully attempt to cut every path in the file, including small imperfections that got traced along with everything else — simpler source images with intentional lines produce more reliable results than complex, noisy photos.

From photo or logo to DXF

Upload the source image (a logo, line drawing, or high-contrast photo works best).
Use Vector Outline mode and adjust threshold/edge smoothness until the traced preview shows clean, continuous lines rather than broken or noisy ones.
Download the DXF file alongside the SVG, and load it directly into your machine's cutting software.

Frequently asked questions

What's the difference between the SVG and the DXF I get?

They describe the same traced shapes — SVG is the general-purpose vector format most design and web tools expect, and DXF is the format most laser engravers, CNC routers, and vinyl cutters expect. Both are generated from the same trace, so you get one for editing/preview and one for the machine.

Do I need a laser engraver already to try this?

No — you can convert and preview the traced result for free before you ever touch a machine, then download the DXF ($0.99) once you're happy with it and ready to cut.
