Convert legacy GIS data
Move Shapefile, FileGDB, and CAD data into GeoJSON or GeoPackage when a web map or modern pipeline needs a different container.
Prepare files for Google Earth
Convert GeoJSON, Shapefile, DXF, or GML into KML when the destination workflow uses Google Earth or KML-compatible mapping tools.
Keep conversion private
The converter pages use browser-local processing so sensitive GIS files can be previewed and exported without a server upload.
Converter FAQ
Questions about converting GIS files online
What GIS formats can I convert online?
GeoDataViewer provides browser-based conversion routes for GeoJSON, Shapefile, KML, GPX, GeoPackage, GML, DXF, CSV, Excel, and other supported GIS formats. Choose a source and destination above to open a focused converter.
Are GIS files uploaded during conversion?
No. The conversion workflow is designed to run locally in your browser with WebAssembly. Your source file stays on your device instead of being sent to a conversion server.
How do I convert a Shapefile to GeoJSON?
Open the Shapefile to GeoJSON converter, add the complete Shapefile package or ZIP archive, preview the layer, and download the GeoJSON output when the local conversion finishes.
Which output format should I choose for a web map?
GeoJSON is a practical choice for small and medium web-map layers. For larger or tiled delivery, consider GeoPackage, FlatGeobuf, MVT, or PMTiles depending on the receiving tool.
