Why convert GeoJSON to KML?

GeoJSON is the web standard, but to view your data in Google Earth or load it into Google My Maps you need KML. Converting lets you turn coordinates, routes and areas from a web map into something you can explore in 3D or share with Google users.

What gets converted

  • Point, LineString and Polygon features become the matching KML geometries.
  • Multi-geometries and geometry collections become a KML MultiGeometry.
  • Each feature’s name and description become the placemark name and description.

Private by design

Your GeoJSON is converted on your device — it is never uploaded to a server.

Frequently asked questions

What becomes the placemark name?
