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.

Shapefile

ESRI Shapefile is a vector data format developed by ESRI and one of the most widely used formats in GIS. A Shapefile actually consists of multiple files: .shp stores geometry, .shx stores spatial index, .dbf stores attributes, and .prj stores coordinate reference system information. Common practice is to package these files into a ZIP archive for distribution. Shapefile supports three basic geometry types: point, line, and polygon.

Conversion trade-offs

FlatGeobuf: limitations to know

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

Shapefile: what you gain

  • Industry standard with the best compatibility for data exchange
  • Excellent read performance, suitable for large-scale datasets
  • Extensive third-party library and tool support

Why convert FlatGeobuf to Shapefile?

Converting FlatGeobuf to Shapefile 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 Shapefile 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 Shapefile 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 Shapefile converter free?

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

Are coordinate systems preserved when converting FlatGeobuf to Shapefile?

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 Shapefile output.
