About

FlatGeobuf

FlatGeobuf is a geospatial data format based on FlatBuffers, designed for efficient geospatial data storage and transmission. It supports spatial indexing (based on Packed Hilbert Curve R-tree) enabling spatial filtering during reads, loading only data for the area of interest. FlatGeobuf is particularly suited for web applications and streaming processing scenarios requiring fast random access to large datasets.

DXF

DXF (Drawing Exchange Format) is a CAD data exchange format developed by Autodesk, the native interchange format for AutoCAD. DXF stores vector graphic data in text format, including points, lines, polygons, text annotations, and layer information. In GIS, DXF is commonly used for data exchange with CAD systems, and many survey and engineering data are provided in DXF format.

Conversion trade-offs

FlatGeobuf: limitations to know

  • Relatively new ecosystem, tool support not as widespread as traditional formats
  • Binary format, not human-readable

DXF: what you gain

  • Supported by virtually all CAD software and many GIS applications
  • Suitable for exchanging data with engineering surveys

Why convert FlatGeobuf to DXF?

Converting FlatGeobuf to DXF is one of the most common workflows in GIS. FlatGeobuf data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while DXF is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your FlatGeobuf files, keeps geometry and attributes intact, and writes clean DXF output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the FlatGeobuf to DXF converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting FlatGeobuf to DXF?

By default the output keeps the source coordinate system. If your FlatGeobuf file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several FlatGeobuf files at once and each one produces its own DXF output.
