How it works

Converts geospatial data between the most used formats: GeoJSON, KML, KMZ, Shapefile and WKT. It is useful for moving layers, routes or polygons from one tool to another —for example, from a GIS Shapefile to a KML for Google Earth, or from a GeoJSON to WKT to store it in a spatial database.

You upload a file or paste the content (depending on the input format), choose the output format and download the result. Text formats like GeoJSON, KML and WKT can also be pasted directly; binary or compressed ones, like Shapefile (.zip) and KMZ, are always loaded from a file.

All conversion happens in your browser: the data is never uploaded to a server. The geometry of the features (points, lines and polygons) and their coordinates in WGS84 (latitude/longitude) are preserved.

Examples

{"type":"Point","coordinates":[-58.3816,-34.6037]}POINT (-58.3816 -34.6037)A GeoJSON point converted to WKT. The order of the coordinates is longitude, latitude.
LINESTRING (-58.37 -34.60, -58.45 -34.61){"type":"LineString","coordinates":[[-58.37,-34.6],[-58.45,-34.61]]}A WKT line converted to GeoJSON, with its two vertices as coordinate pairs.

Use cases

  • Convert a Shapefile to KML or KMZ to open it in Google Earth or Google Maps.
  • Convert a GeoJSON to WKT to insert it into a geometry column in PostGIS, MySQL or SQL Server.
  • Export a layer drawn in a web editor as a Shapefile to import it into QGIS or ArcGIS.
  • Transform a received KMZ to GeoJSON to use it in a map library like Leaflet or OpenLayers.

Frequently asked questions

What is the difference between KML and KMZ?

KML is a plain-text XML file; KMZ is exactly the same but compressed in a ZIP (and can include resources such as icons or images). KMZ takes up less space and is more convenient to share.

Why is the Shapefile loaded and downloaded as a .zip?

A Shapefile is not a single file, but a set (.shp, .shx, .dbf, .prj, etc.) that must travel together. That is why it is grouped into a ZIP both to load it and to download the result.

What coordinate system is used?

Coordinates are handled in WGS84 (EPSG:4326), the latitude and longitude system used by GeoJSON, KML and most web maps. If your Shapefile comes in another projection, it is advisable to reproject it beforehand in a GIS.

Are my files uploaded to a server?

No. The conversion is done entirely in your browser; the geospatial data never leaves your device.
