OSM map: get DXF (AutoCAD) instead of converting TopoJSON → DXF
Looking to turn a map from TopoJSON into DXF? If your data comes from OpenStreetMap, you do not need an intermediate TopoJSON file: osm2cdr builds the map straight from the OSM source and hands you a ready DXF, which opens in AutoCAD. That is faster and more accurate than the chain "download TopoJSON → upload to a converter → get DXF": you pick an area on the map, choose the DXF format and download the result with up-to-date OSM data and layers for buildings, roads, water and features.
How TopoJSON differs from DXF
| Format | Extension | Type | Purpose |
|---|---|---|---|
| TopoJSON | .topojson | GIS | Choropleth maps, D3.js visualization, administrative boundaries, compact maps |
| DXF | .dxf | CAD | Site plans, engineering surveys, importing maps into AutoCAD, land planning |
How to get DXF on osm2cdr
- 1Select an area on the map on the osm2cdr home page
- 2Choose the DXF format and, if needed, a style and CRS
- 3Click Export and download the ready DXF file

When you need DXF
The DXF format is handy when you need to open the result in a dedicated program and keep working with the map: editing, printing, analysing or embedding it in a project. osm2cdr delivers DXF split into layers with up-to-date OpenStreetMap data, so the file is ready to use right after download.
What changes when going TopoJSON → DXF
Going TopoJSON → DXF, GIS attribute tables are not carried into the drawing: geometry is laid out across named layers (buildings, roads, water) while coordinate accuracy is preserved. The result targets CAD work, not attribute analysis. osm2cdr builds DXF straight from OpenStreetMap data, so an intermediate TopoJSON file is not needed.
If you have your own TopoJSON file (not from OSM)
osm2cdr does not accept or convert third-party TopoJSON files: the service works only with OpenStreetMap data. If you already have your own TopoJSON file that is not from OSM, convert it to DXF with third-party tools: GDAL/ogr2ogr from the command line or QGIS — open the TopoJSON and save the layer as DXF. It is free and runs locally, with no cloud upload.
FAQ: TopoJSON → DXF
Can I upload my TopoJSON file?
Not yet: we don't support uploading TopoJSON files at the moment, so convert your file to DXF with ogr2ogr or QGIS. And if your data comes from OpenStreetMap, you don't need a file at all — osm2cdr exports the map straight into DXF.
Is it free?
Yes, exporting an OpenStreetMap map to DXF on osm2cdr is free. Select an area, the DXF format and download the result.
Which programs open DXF?
The DXF format opens in dedicated programs for its category. See the DXF format page for the full list and details.
Why is this better than an online TopoJSON → DXF converter?
An online converter caps the result quality at the quality of the source TopoJSON file. osm2cdr takes data from the OpenStreetMap source and builds DXF with correct layers directly — with no loss on an intermediate TopoJSON file.
