Free CAD to GeoJSON Converter

Convert DXF and DWG drawings to GeoJSON, keeping every layer, block and attribute. Optionally reproject from your CAD coordinate system to WGS84. Everything runs in your browser — your files are never uploaded, and no external service is used.

1. Choose a CAD file

2. Coordinate system

When a coordinate system is chosen, every coordinate is reprojected to WGS84 longitude/latitude, as the GeoJSON specification expects.

3. Conversion options

Upload a DXF or DWG file to get started.

Converted in your browser. Your CAD files never leave your device.

DXF & DWG

DXF files are parsed directly. DWG files are converted with LibreDWG compiled to WebAssembly — the DWG engine is downloaded only when you open a DWG, so DXF stays fast.

Every property kept

Layer, entity type, handle, colour, linetype, lineweight, text, block name and any block attributes or XDATA are written into each GeoJSON feature's properties.

Private & offline

No uploads and no external API. Your drawings are processed locally, so even confidential designs stay on your machine.
