About

GeoPackage

GeoPackage is an open standard defined by OGC, implemented on SQLite database technology. It is a single container file that can simultaneously store vector features, raster imagery, attribute tables, and map tiles. GeoPackage requires no database server and can be used directly on mobile devices and desktop applications, making it an ideal choice for modern GIS data exchange.

KML

KML (Keyhole Markup Language) is an XML-based geographic markup language originally developed by Keyhole and later acquired by Google, becoming an OGC standard. KML can describe points, lines, polygons, image overlays, 3D models, and other rich geographic content. It is the native format for Google Earth and Google Maps. KML files organize geographic data using tags and attributes, and support style definitions and network link functionality.

Conversion trade-offs

GeoPackage: limitations to know

  • Does not support concurrent multi-user writes
  • Single database file size limited by SQLite constraints

KML: what you gain

  • Deep integration with Google ecosystem, can be displayed directly in Google Earth
  • Supports NetworkLink for dynamic data updates

Why convert GeoPackage to KML?

Converting GeoPackage to KML is one of the most common workflows in GIS. GeoPackage data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while KML is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your GeoPackage files, keeps geometry and attributes intact, and writes clean KML output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the GeoPackage to KML converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting GeoPackage to KML?

By default the output keeps the source coordinate system. If your GeoPackage file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several GeoPackage files at once and each one produces its own KML output.
