GeoJSON is a geospatial data interchange format based on JSON. It can represent Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection geometries. Defined by RFC 7946, GeoJSON has become one of the most popular data exchange formats in web GIS. GeoJSON files use WGS84 coordinates and support Feature objects with associated properties and FeatureCollections for organizing multiple features.
KML (Keyhole Markup Language) is an XML-based geographic markup language originally developed by Keyhole and later acquired by Google, becoming an OGC standard. KML can describe points, lines, polygons, image overlays, 3D models, and other rich geographic content. It is the native format for Google Earth and Google Maps. KML files organize geographic data using tags and attributes, and support style definitions and network link functionality.
Google Earth remains the easiest way for non-GIS people to explore geographic data — and it only speaks KML. When you need to show a dataset to stakeholders, clients, or a community group, converting GeoJSON to KML lets them open it in a tool they already know, with placemarks, lines, and polygons rendered exactly as drawn. It is also the standard route for getting web-originated data onto Google My Maps.
Yes. Feature properties are written into the KML description, so clicking a placemark in Google Earth shows all attribute data.
Points, LineStrings, Polygons and Multi-variants are all converted to the matching KML geometry types.
Yes — KML is the native import format for My Maps, so the converted file can be loaded directly.
Upload your GeoJSON file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the KML file. Each input produces its own output, ready to use in your GIS, web map, or archive.
