About

TopoJSON

TopoJSON is a GeoJSON extension developed by Mike Bostock that encodes topology to eliminate redundant shared boundaries. Unlike GeoJSON where each polygon independently stores all vertices, TopoJSON uses arcs to share common boundaries between adjacent features, reducing file sizes by over 80%. TopoJSON is particularly suited for rendering large numbers of adjacent areas such as administrative district maps.

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

TopoJSON: limitations to know

  • Smaller ecosystem, tool support not as widespread as GeoJSON
  • Requires additional decoding step for map rendering

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 TopoJSON to Shapefile?

Converting TopoJSON to Shapefile is one of the most common workflows in GIS. TopoJSON 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 TopoJSON 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 TopoJSON to Shapefile converter free?

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

Are coordinate systems preserved when converting TopoJSON to Shapefile?

By default the output keeps the source coordinate system. If your TopoJSON 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 TopoJSON files at once and each one produces its own Shapefile output.

How to Use

  1. 1

    Upload your TopoJSON 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 Shapefile file. Each input produces its own output, ready to use in your GIS, web map, or archive.
