What is the difference between GeoJSON and KML?
GeoJSON integrates natively with Leaflet, Mapbox, PostGIS, and JavaScript pipelines, whereas KML targets Google Earth globes and styled XML placemarks. On the points that matter most: Serialization — GeoJSON: Lightweight JSON (RFC 7946); KML: Verbose XML (OGC KML 2.2). CRS specification — GeoJSON: Strict WGS84 (EPSG:4326); KML: WGS84 + altitude modes. Web GIS ecosystem — GeoJSON: Native in Leaflet/Turf/MapLibre; KML: Google Earth & desktop GIS.
Is GeoJSON better than KML?
Standardize on GeoJSON for web maps, APIs, and spatial data pipelines; export KML when delivering placemarks and paths to Google Earth users. If you mainly need the core feature without a subscription or signup, GIS GeoJSON, KML, GPX & WKT Converter Studio is a free alternative to both.
Is there a free alternative to both GeoJSON and KML?
Yes — our GIS GeoJSON, KML, GPX & WKT Converter Studio is completely free with no account required.
