Tip: The KMZ is unzipped and read in your browser, then written as a single GeoPackage layer in WGS 84, ready for QGIS or ArcGIS Pro.
KMZ is simply a KML file (plus any referenced icons or overlays) compressed into a single ZIP archive with a .kmz extension. It's the format Google Earth produces when you save a place, because bundling everything into one compact file makes maps easy to email and share. Under the hood it's still KML, so a KMZ converts cleanly to and from every other geographic format.
Need the other direction instead? GeoPackage is the OGC's single-file GIS format, and QGIS's default. GeoPackage (.gpkg) is an open OGC standard that stores vector layers, attribute tables and map tiles in a single SQLite database file. It's the default save format in QGIS and is read by ArcGIS Pro, GDAL and most modern GIS software. Unlike a shapefile, one GeoPackage can hold many layers, has no 10-character limit on field names, and keeps everything in one file instead of a bundle of sidecar files.
The GeoPackage is written as one layer in WGS 84 (EPSG:4326), with attribute types (text, integer, decimal) detected from your data.

KMZ to GeoPackage — FAQ
- How do I convert KMZ to GeoPackage?
- Upload your .kmz file using the converter above (drag & drop or click to browse). GeoMaps converts it to GeoPackage instantly in your browser and gives you a .gpkg file to download. No software to install and no signup required.
- Is the KMZ to GeoPackage converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert GeoPackage back to KMZ?
- Yes. Use our GeoPackage to KMZ converter for the reverse conversion — every format on GeoMaps converts both ways.
- Anything to know about GeoPackage output?
- The GeoPackage is written as one layer in WGS 84 (EPSG:4326), with attribute types (text, integer, decimal) detected from your data.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
