How to Convert Google Earth Files for Web Mapping
Learn how to convert KML and KMZ files from Google Earth to web-friendly formats for modern mapping applications.
Why Convert Google Earth Files?
Google Earth uses KML (Keyhole Markup Language) and KMZ (compressed KML) formats, which are excellent for Google Earth but may not be ideal for web mapping applications. Converting these files to formats like GeoJSON, Shapefile, or GPX opens up new possibilities for your geographic data.
Common Conversion Scenarios:
- • Using Google Earth data in Leaflet or Mapbox web maps
- • Importing into mapping software like QGIS or ArcGIS
- • Converting for mobile mapping applications
- • Preparing data for web APIs and databases
Understanding Google Earth File Types
KML Files (.kml)
- • XML-based format
- • Human-readable text
- • Contains geographic data and styling
- • Supports placemarks, paths, and polygons
- • Can include descriptions and multimedia
KMZ Files (.kmz)
- • Compressed KML archive
- • Contains KML + associated files
- • Includes images, icons, and overlays
- • Smaller file size than KML
- • Standard ZIP compression
Popular Conversion Formats
KML/KMZ → GeoJSON
Perfect for web mapping applications, APIs, and JavaScript-based maps.
KML/KMZ → Shapefile
Industry standard for mapping software like QGIS, ArcGIS, and desktop mapping tools.
KML/KMZ → GPX
Ideal for GPS devices, fitness trackers, and navigation applications.

Tips for Better Conversions
Before Converting:
- • Clean up unnecessary folders in Google Earth
- • Remove or simplify complex styling
- • Check for coordinate system compatibility
- • Verify data accuracy and completeness
After Converting:
- • Test the converted file in your target application
- • Verify that all features are preserved
