Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your KML files to GeoJSON format effortlessly to ensure compatibility with modern web mapping libraries. This tool is essential for GIS developers and researchers who need to transition from Google Earth data to standardized web-ready geometry formats.
KML (Keyhole Markup Language) is an XML-based format primarily used by Google Earth, while GeoJSON is a lightweight, JSON-based standard favored by web mapping APIs like Leaflet, Mapbox, and OpenLayers. During conversion, our tool maps KML’s hierarchical structure and specific metadata tags into the flat, standardized feature collection format required by GeoJSON, ensuring coordinate systems are properly projected to WGS84.
Geometric accuracy is fully preserved, though complex KML-specific styles (like balloon templates or specialized icons) may be stripped as GeoJSON focuses primarily on geographic data and simple properties.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
