DXF Converter — Convert DXF Files Online Free
DXF (Drawing Exchange Format) is AutoCAD's file exchange format, widely used in civil engineering, surveying, and architecture. Maparz converts DXF files to GIS formats and converts GIS data to DXF for use in AutoCAD, BricsCAD, and QCAD — powered by GDAL's DXF driver.

About DXF format
Drawing Exchange Format (DXF) is the open interoperability format developed by Autodesk for AutoCAD. It is widely used in civil engineering, architecture, and urban planning workflows. DXF files contain geometric primitives like lines, arcs, polylines, and text. When converting DXF files to GIS formats like Shapefile or GeoJSON, the geometry is preserved but attribute data may be minimal since DXF layers are mapped to feature properties. Conversely, GIS data exported to DXF can be brought into CAD workflows for drafting.

Frequently asked questions
Q.What DXF entity types are supported?
GDAL supports POINT, LINESTRING (LINE and LWPOLYLINE), and POLYGON entities. Complex entities like HATCH, BLOCK references, and XREF are not supported.
Q.Why are my DXF coordinates wrong after conversion to GeoJSON?
DXF files do not always contain CRS metadata. If coordinates appear correct in AutoCAD but wrong in GIS, the DXF may be in a projected CRS rather than WGS 84. Define and transform the CRS after conversion.
Q.Can I convert GeoJSON back to DXF for AutoCAD?
Yes. Maparz converts GeoJSON, Shapefile, KML, and GeoPackage to DXF. Output uses LWPOLYLINE and POINT entities compatible with AutoCAD and other CAD tools.
