When to use this converter
Convert GeoJSON to KML to visualize web mapping data in Google Earth or share it via Google My Maps. Perfect for: displaying Mapbox or Leaflet maps in Google Earth, sharing spatial analysis results with non-technical users via Google Maps, or converting GIS exports for easy viewing on any device with Google Earth installed.
What gets converted
All coordinate data, feature types, and properties are preserved. Points, LineStrings, and Polygons map directly to KML equivalents. GeoJSON properties become KML ExtendedData or description text. Simple styling information is converted when possible. Complex GeoJSON features like GeometryCollections are split into individual KML features.
Frequently Asked Questions
Can I view my GeoJSON in Google Earth after converting?
Yes. KML is Google Earth's native format. Once converted, you can open the KML file directly in Google Earth or import it into Google My Maps for web-based viewing and collaboration.
What happens to GeoJSON properties during conversion?
GeoJSON properties are converted to KML's ExtendedData or used in the description field. Coordinate data, feature names, and geometry types are fully preserved. Complex nested properties may be flattened for KML compatibility.
Is the conversion process secure?
Yes. All processing happens client-side in your browser. Your GeoJSON file is never uploaded to any server, ensuring your geographic data remains private and secure.
Can I style the features after conversion?
The converter preserves basic styling when possible, but you can further customize colors, icons, and line styles by editing the KML in Google Earth or Google My Maps after conversion.
