KML to GeoJSON converter
Drop a KML file to see it on the map and download it as GeoJSON. Placemarks, paths and polygons (with their holes) become GeoJSON features; names, descriptions and ExtendedData become properties, and styles become simplestyle properties where they map.
The file is read and converted in your browser; nothing is uploaded.

How do I convert KML to GeoJSON?

What carries over from KML to GeoJSON?
Placemarks, paths and polygons (with their holes) become GeoJSON features; names, descriptions and ExtendedData become properties, and styles become simplestyle properties where they map.
What does not carry over?
Network links and ground overlays are not followed. KMZ files are unzipped in your browser first.
What is a KML file?
KML is Google Earth's format (KMZ is the same zipped): placemarks, paths and polygons with names, descriptions and styles.
Is it free? Is there a size limit?
Free, with no account. There is no upload limit because nothing is uploaded; very large files (hundreds of megabytes) are limited only by your browser's memory.
Is there an app?
Not for this tool yet. The nearest is GPX Explore, on iPhone, iPad and Mac, which opens any GPX file with the track coloured by grade, every sensor charted and a workout summary. Free. App Store · Mac App Store · More about GPX Explore
