PNG to DXF Converter

Convert PNG images to DXF format. Automatically traces PNG raster images into vector outlines, then exports as DXF for CNC and CAD use.

How to Use

Upload PNG image

Upload a high-contrast PNG image (black on white works best).

Adjust tracing settings

Set threshold, smoothing, and curve tolerance for the auto-trace.

Download DXF

Download the traced DXF file for use in CNC or CAD software.

How PNG to DXF Conversion Works

Unlike SVG-to-DXF conversion (which converts existing vector data), PNG-to-DXF requires an additional step: image tracing (also called vectorisation or raster-to-vector conversion). This process analyses pixel values in the PNG, identifies edge contours, and converts those contours into vector paths.

The resulting vector paths are then exported as DXF entities — typically polylines or splines — which can be imported into any CAD or CNC software. The quality of the output depends heavily on the input image quality. For best results, use high-resolution, high-contrast images with clean edges.

Real-World Examples & Use Cases

Logo Cutting

Convert a PNG company logo to DXF for cutting on a vinyl cutter or CNC router.

Scanned Drawing to CAD

Scan a hand-drawn sketch, clean it up in an image editor, then convert the PNG to DXF for use in AutoCAD.

Frequently Asked Questions

What images work best?▼

High-contrast images with clear edges produce the best traces. Black silhouettes on white backgrounds are ideal. Avoid photographs or complex gradients.

How accurate is the auto-trace?▼

For clean line art, the trace is highly accurate. For complex artwork or low-contrast images, manual cleanup in a CAD tool may be needed.

What is the tracing algorithm used?▼

We use a browser-side implementation of the Potrace algorithm, the same engine used by Inkscape's "Trace Bitmap" feature.
