How to Convert DWG to GeoJSON (Online, No Upload)

Convert DWG to GeoJSON step-by-step in your browser. Preview the layer, export GeoJSON, and troubleshoot common DWG conversion issues.

If you need to convert DWG to GeoJSON for web maps or GIS pipelines, the fastest workflow is: export the DWG as DXF from your CAD software, preview the layer, confirm geometry looks right, then export as GeoJSON.

DWG is a proprietary format, so browser converters work with its open counterpart, DXF. GeoDataViewer lets you do the conversion in the browser without installing desktop GIS software:

Why convert DWG to GeoJSON?

GeoJSON is a common interchange format for:

  • Web maps and APIs
  • Lightweight data sharing
  • Front-end debugging and quick inspection

Step-by-step: DWG to GeoJSON (via DXF)

  1. In AutoCAD, BricsCAD, or QGIS, export your drawing as .dxf.
  2. Open the converter: /dxf-to-geojson/
  3. Upload your .dxf file.
  4. Preview the data in the map to confirm position and scale.
  5. Export the generated GeoJSON file.

Common issues and tips

Data appears offset or in the wrong place

CAD drawings may not include clear CRS metadata. If a DWG is in a local engineering coordinate system, you may need a known CRS or reference to correctly align it.

Too many layers or messy geometry

DWG files often contain multiple layers with different purposes. If possible, export a cleaner version from the source CAD environment before conversion.
