GeoJSON is an open standard (RFC 7946) for representing geographic features — points, lines and polygons — together with their attributes as plain JSON. It's the lingua franca of modern web mapping: readable by virtually every GIS tool, library (Leaflet, Mapbox GL, OpenLayers, deck.gl) and programming language out of the box. Its simplicity and human-readability make it the natural hub format to convert to and from.
Need the other direction instead? KML is google Earth's XML format for placemarks and overlays. KML (Keyhole Markup Language) is an OGC standard XML format created for Google Earth and used widely across Google Maps, mobile mapping apps and GIS software. It stores placemarks, paths, polygons, styling and folder structure, which makes it ideal for sharing annotated maps with non-technical audiences. A KML file is plain text; when zipped with its assets it becomes a KMZ.

GeoJSON to KML — FAQ
- How do I convert GeoJSON to KML?
- Upload your .geojson file using the converter above (drag & drop or click to browse). GeoMaps converts it to KML instantly in your browser and gives you a .kml file to download. No software to install and no signup required.
- Is the GeoJSON to KML converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert KML back to GeoJSON?
- Yes. Use our KML to GeoJSON converter for the reverse conversion — every format on GeoMaps converts both ways.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
