How to convert GeoJSON to KML

  1. Drop your GeoJSON file into the box above (or click to browse).
  2. The GDAL engine loads once and reads the file right in your browser.
  3. Pick KML as the output, set a coordinate system if you need one, and click Convert, then download the result.

Why convert GeoJSON to KML?

GeoJSON is a vector GIS format, so it isn't always the format the next tool expects. Converting it to KML lets you open and view it in Google Earth or Google Maps 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.

About the formats

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.

KML (.kml): KML is the XML-based format Google Earth and Google Maps use to describe points, lines, polygons, labels and styling. Because it is plain text it is easy to read, edit and share, and it stores coordinates in WGS84 longitude/latitude by default.

What is a GeoJSON file?

GeoJSON is an open, JSON-based standard (RFC 7946) for encoding vector features and their attributes.

Can I set the coordinate system?
