How do I convert png to dxf autocad on Windows PC?

Adobe Illustrator + a DXF export plugin.

Illustrator can open some simple DXF files, but it lost native DXF/DWG export in recent versions (older CS versions had it, current Creative Cloud versions don't). So you need a workaround: a plugin, a script, or exporting to an intermediate format another tool converts.

How to convert png to dxf on Windows

Place the PNG in a new document (File → Place.)

Select it, open Window → Image Trace.

Choose a preset — "Black and White Logo" for simple line art, "High Fidelity Photo" for complex images — then adjust threshold, paths, and corners sliders until the tracing looks clean.

Click Object → Image Trace → Expand to convert the trace into actual editable vector paths.

Scan2CAD's Illustrator plugin — adds a direct DXF/DWG export command inside Illustrator. This is the most seamless option if you're already committed to Illustrator's tracing engine.

One caution: whichever route you use, double-check units (mm vs inches) and that paths are closed before sending the DXF to a CNC or laser cutter — this is the most common source of errors in PNG to DXF conversions.
