GeoJSON is an open standard format based on JSON for representing simple geographical features along with their non-spatial attributes. It is widely used in web mapping applications and supported by most GIS software including QGIS, Mapbox, and Leaflet.
KML (Keyhole Markup Language) is an XML-based format for representing geographic data. It is the standard format for Google Earth and Google Maps, and is used extensively in GIS applications for sharing geographic annotations and visualizations.
Converting GeoJSON to KML allows you to open your geographic data in Google Earth, share it with users who prefer KML-based workflows, and integrate with legacy GIS systems that primarily support KML. KML also supports rich styling and 3D visualization features.
Yes. GeoDataTools performs all conversions entirely in your browser using JavaScript. Your files never leave your device — no data is uploaded to any server. This makes it ideal for handling sensitive or proprietary geographic data.
This converter supports all standard GeoJSON geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. All properties and attributes are preserved in the KML output as ExtendedData.
GeoDataTools supports files up to 30MB. For larger files, consider splitting your data into smaller chunks or using the full GeoDataTools app which uses Web Workers for optimal performance.
