How to convert PNG to DXF

Upload your PNG file

Drop your .png on the converter, click to browse, or paste a screenshot with Ctrl+V.

We trace the lines

Transparency is flattened to white, then thin lines are reduced to single centerline paths and solid areas are outlined — the two things a cutter needs kept apart.

Download a real DXF

You get an R2000 ASCII DXF with editable LWPOLYLINE geometry — the open CAD exchange format — editable geometry, ready to draft on, not a picture to trace again.

What you get: lines, not pictures

A floor plan with solid walls, furniture and text — and the CAD geometry this converter produces from it. Walls keep both faces, every thin line is a single editable polyline, and labels become real editable text.

Example PNG floor plan before conversion — Input: raster image (solid walls, thin furniture lines, text)

Editable DXF vector drawing produced by the converter — Output: editable DXF polylines (walls outlined, lines centerlined)

About PNG to DXF conversion

DXF is the format the fabrication world runs on. LightBurn, VCarve, plasma table controllers, vinyl cutters and every CAD package on the market read it, which is why "PNG to DXF" is the single most searched conversion this site handles. What people actually want from it is rarely a drawing to look at — it is a toolpath source, and that raises the bar. A cutter will follow whatever it is given, so a trace full of doubled lines or artifact specks becomes wasted material.

PNG is the right raster to start from. It is lossless, so line edges are exactly where the source put them and there is no ringing to strip. Transparency is composited onto white first, since DXF has no alpha. The output is an R2000 ASCII DXF — plain text, maximum compatibility, opened without complaint by twenty-year-old machine software as readily as by current CAD. Thin lines come back as single centerline polylines and solid regions as closed outlines along their real edges, which is the distinction that decides whether a cut path is one pass or two.

Frequently asked questions

Will the DXF cut correctly on a laser or CNC?

The geometry is real closed and open polylines, so LightBurn, VCarve and machine controllers read it directly. Always check the trace before cutting: solid areas come back as outlines with both edges, so decide whether you want to cut the outline or fill it before you send the job.

Which DXF version is produced?

R2000 ASCII DXF. It is plain text and the most widely supported variant there is — opened by current CAD packages as happily as by decade-old machine software that chokes on newer binary variants.

Does PNG transparency cause problems in the DXF?

No. DXF has no alpha channel, so transparent pixels are composited onto white before thresholding. A logo exported on a transparent background produces the same DXF as one exported on a white one.

Can I convert a PNG screenshot to DXF?

Yes — screenshots are lossless, which is what matters most. The limit is resolution: the image is normalized to a 2048-pixel working frame, so capture as large as you can. A 500-pixel screenshot of a detailed plan will lose its fine lines.

Is there a free limit or a watermark?

Neither. No account, no daily cap, no watermark, no locked export. Files up to 100 MB, as many as you want. Uploads and results are retained so failures can be debugged and results re-downloaded; they are never sold or shared.
