GeoJSON to KML Converter
Geographic JSON (GeoJSON) is the format used by Mapbox, Leaflet, QGIS, PostGIS, and any modern web-mapping stack. Keyhole Markup Language (KML) is what people sharing places with Google Earth users or importing into Google My Maps need. This free converter takes a GeoJSON file and produces a ready-to-use .kml on the spot — everything runs in your browser, so your data never touches our server. Drop a file or paste text on the left, click convert, copy or download the result on the right.
Frequently asked questions
How do I convert GeoJSON to KML?
Open this page, paste your GeoJSON text or drop your .geojson file into the input panel, keep the dropdown set to GeoJSON on the left and KML on the right, then click Convert. The .kml output appears on the right; copy it to your clipboard or download the file.
Is this GeoJSON-to-KML converter free?
Yes, completely free. No signup, no watermark, no upload limits. The conversion runs entirely in your browser using open-source libraries.
Does my file get uploaded anywhere?
No. The converter is fully client-side — your GeoJSON file is parsed by JavaScript running in your own browser tab and never leaves your computer. We have no server-side processing for these tools.
What's the difference between GeoJSON and KML?
GeoJSON is a lightweight JSON-based standard. It's what modern web maps speak natively, with first-class support in Mapbox, Leaflet, and PostGIS. KML is an XML-based format from Google. It supports rich styling, folders, and 3D extrusions, but it's tied to Google Earth conventions.
Can I convert KML back to GeoJSON?
Yes — switch the dropdowns or open our /tools/kml-to-geojson/ page. We support every directional pair between KML, GPX, GeoJSON, CSV, and Excel.
Need to export from Google Maps?
ExportMyMap pulls your starred and saved places directly from Google Maps and gives you the same five formats this converter speaks — plus a shareable link and a printable PDF.
