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.

KMZ

KMZ is the compressed archive format of KML, packaging the .kml file and its associated images, icons, and other resources into a single ZIP archive. KMZ files are smaller and easier to distribute via email or web download. Google Earth can open KMZ files directly, automatically extracting and rendering the geographic content.

Conversion trade-offs

GeoPackage: limitations to know

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

KMZ: what you gain

  • Single file containing all content, easy to distribute
  • Significantly smaller file size after compression

Why convert GeoPackage to KMZ?

Converting GeoPackage to KMZ 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 KMZ 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 KMZ 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 KMZ converter free?

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

Are coordinate systems preserved when converting GeoPackage to KMZ?

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 KMZ output.
