GeoJSON to KML Converter
Take GeoJSON data from a web map and open it in Google Earth as KML. Runs entirely in your browser, nothing is sent anywhere.
Your files never leave this tab
There is no upload. Files are read by the code already running on this page, processed in memory, and handed straight back to you as a download. This tool has no server that accepts your data and nothing is written to storage.
Want proof? Turn off your Wi-Fi, then convert. It still works, because the work happens on your device.

Why convert GeoJSON to KML
GeoJSON is easy to generate from code but Google Earth cannot open it directly. Converting to KML is the usual bridge when you want to inspect or present map data authored for the web inside Earth's 3D viewer instead.
Curious how the conversion itself works with nothing ever uploaded? Read how TrailConvert works.
