About

AutoCAD DWG

DWG (Drawing) is Autodesk AutoCAD's native binary design file format, the most widely used format in engineering design and drafting. DWG files contain rich design information including vector graphics, text annotations, layer definitions, and block references. Vector features from DWG can be extracted to standard GIS formats through GDAL/OpenDesign libraries.

GeoJSON

GeoJSON is a geospatial data interchange format based on JSON. It can represent Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection geometries. Defined by RFC 7946, GeoJSON has become one of the most popular data exchange formats in web GIS. GeoJSON files use WGS84 coordinates and support Feature objects with associated properties and FeatureCollections for organizing multiple features.

Conversion trade-offs

AutoCAD DWG: limitations to know

  • Proprietary binary format, parsing relies on third-party libraries
  • Coordinate system information usually incomplete, manual specification needed

GeoJSON: what you gain

  • Human-readable, easy to manually edit and debug
  • Supported by virtually all GIS software and mapping libraries
  • Naturally suited for web applications and API data transmission

Why convert AutoCAD DWG to GeoJSON?

DWG is the native, proprietary format of AutoCAD — the file every architecture, engineering, and surveying office produces. Because it is closed, web tools usually refuse it. Converting DWG to GeoJSON unlocks those drawings for GIS and web mapping: building outlines, pipe networks and survey lines become GeoJSON features with layer metadata, ready for QGIS, Leaflet, or PostGIS — all parsed locally in your browser so the drawing never leaves your machine.

Frequently asked questions

Which DWG versions are supported?

Common releases in modern use are supported. Very old or newest-day-one releases may not be; exporting a DXF from AutoCAD is a reliable fallback.

Are text and annotations included?

Text entities are converted as point features carrying the text string as a property, so labels are not silently lost.

Is a DWG with external references (XREFs) handled?

Only geometry stored inside the file is converted. Attach external references before converting if they must appear in the output.

GeoJSON at a glance

Key Features

  • Based on standard JSON, natively supported by all programming languages
  • Supports multiple geometry types: Point, LineString, Polygon, MultiPolygon, etc.
  • Can carry attribute data and supports FeatureCollection for batch organizing features

Common Use Cases

  • Data exchange for web maps and online mapping services
  • Geospatial data storage and display in mobile applications
  • Sharing and transporting GIS data across platforms

How to Use

  1. 1

    Upload your AutoCAD DWG file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.

  2. 2

    The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.

  3. 3

    Download the GeoJSON file. Each input produces its own output, ready to use in your GIS, web map, or archive.
