Why Use Our KML to GeoJSON Converter?
KML is heavily reliant on XML structures, making it cumbersome to use in modern web development. When building interactive maps using libraries like Leaflet, Mapbox, or OpenLayers, developers vastly prefer lightweight JSON structures.
Converting KML to GeoJSON modernizes your geographic data. GeoJSON is faster to parse, natively supported by JavaScript, and has become the de facto standard for building dynamic, interactive web mapping experiences.

Frequently Asked Questions
Are styling elements preserved?
GeoJSON focuses strictly on spatial data (geometry) and properties. Custom styling elements from KML (like icon colors) are mapped to the properties object, but you must apply styling manually in your map engine.
Does it support polygons and multi-geometries?
Yes, complex KML geometries including Polygons, LineStrings, and MultiGeometries are fully supported and accurately mapped to their GeoJSON equivalents.
Why is GeoJSON better for web apps?
GeoJSON is natively parsed by browsers as a standard JavaScript object, making it significantly faster and easier to manipulate with code compared to parsing XML documents.
