Convert GeoJSON files to KMZ, online and free. GISConverter reads your GeoJSON data locally in the browser and writes a KMZ file so you can share it as a single, compact Google Earth file — nothing is uploaded, and your data never leaves your computer.

GeoJSON is a vector GIS format, so it isn't always the format the next tool expects. Converting it to KMZ lets you share it as a single, compact Google Earth file without redrawing or re-collecting anything. Because GISConverter runs a full GDAL engine in your browser, the geometry and attributes carry across faithfully, and the file never leaves your device.
GeoJSON (.geojson): GeoJSON is an open, JSON-based standard (RFC 7946) for encoding vector features and their attributes. It is human-readable, works natively in JavaScript, and is the default vector format of the modern web-mapping stack, so nearly every web map and API speaks it.
KMZ (.kmz): A KMZ file is simply a KML document compressed into a ZIP archive, optionally bundling icons, images and overlays alongside it. It is smaller than raw KML and is the format Google Earth exports by default, which makes it the usual way to hand a finished map to someone else.
Yes. GISConverter is completely free and runs in your browser — no signup, no watermark, and no daily limit.
No. Your GeoJSON file is read and converted locally on your device with a GDAL engine compiled to WebAssembly, so it never leaves your computer.

Yes. Output defaults to EPSG:4326 (WGS84 longitude/latitude). Enter any EPSG code, such as EPSG:3857, in the coordinate-system box to reproject on the way out.
