GPKG (GeoPackage) is an open, SQLite-based container for storing geospatial data such as vector features, tiles, and attributes in a single portable file. KMZ is a compressed KML package used by Google Earth and other mapping tools to share geographic data, placemarks, paths, polygons, and overlays.
Why convert gpkg to kmz
Converting GPKG to KMZ is useful when you need to share GIS data in a format that is easier to open in Google Earth or distribute as a compact map package. KMZ is especially convenient for visualization, while GPKG is better suited for GIS editing and storage.
Best software for conversion
The most reliable option is QGIS, because it supports both formats and gives you control over coordinate systems, styling, and attribute export. For command-line workflows, GDAL/OGR is also an excellent choice.
Recommended software: QGIS
Alternative: GDAL/OGR
How to convert gpkg to kmz in qgis
- Open QGIS and load your GPKG layer.
- Right-click the layer and choose Export → Save Features As...
- Set the format to KML if available, or export to KML first and then package it as KMZ.
- Choose the correct coordinate reference system, usually WGS 84 (EPSG:4326), which is required for Google Earth compatibility.
- Save the exported file.
- If needed, compress the resulting .kml file and any related assets into a .kmz archive.
How to convert gpkg to kmz with gdal
Using GDAL, you can convert the layer from GeoPackage to KML, then package it as KMZ if your workflow requires a compressed output.
ogr2ogr -f KML output.kml input.gpkgIf you need a KMZ package, place the KML and any linked resources into a ZIP archive and rename it with the .kmz extension, or use a tool that writes KMZ directly.
Important conversion notes
- Coordinate system matters: KMZ/KML works best in WGS 84.
- Styling may change: Some advanced GPKG symbology does not transfer perfectly to KMZ.
- Attribute support is limited: KMZ is mainly for visualization, not full GIS editing.
- Large datasets: Simplify or filter features before export for better performance in Google Earth.
When to use online converters
Online converters can be convenient for small, non-sensitive datasets, but they are usually less suitable for professional GIS work. For accuracy, privacy, and control, QGIS or GDAL is the better choice.
Summary
GPKG to KMZ conversion is best handled in QGIS for a user-friendly workflow or GDAL/OGR for automation. Export in WGS 84, check styling, and package the result for use in Google Earth.
