About KMZ

KMZ is a ZIP archive that wraps a KML document plus any referenced icons or overlays. It is the format Google Earth uses for sharing complete documents with imagery in a single file.

Typical producers: Google Earth, Google My Maps.
Typical consumers: Google Earth, Google Maps.

About GeoPackage

GeoPackage (.gpkg) is an OGC standard that stores many layers — vector and raster — inside a single SQLite database with spatial indexes. It scales far beyond Shapefile and is the recommended format for GIS exchange today.

Typical producers: QGIS, OGR/GDAL, PostGIS, GeoServer.
Typical consumers: QGIS, ArcGIS Pro, GDAL, Mapbox Tippecanoe.

How to convert KMZ to GeoPackage

  1. Drop your KMZ file (.kmz) on the area above, or click to browse.
  2. The file is parsed server-side — geometries are normalised to a GeoJSON FeatureCollection internally, then written out as GeoPackage.
  3. The converted file downloads automatically. No retention; nothing is kept on the server.

Want to inspect the geometry before converting? Use the full 3D viewer instead — it renders the file on a MapLibre globe with toggleable layers, then lets you convert from the same toolbar.

FAQ

Is the KMZ to GeoPackage converter free?

Yes. rooot viewer is free and requires no account. There are no per-conversion charges.

Do I need to install software?

No. The conversion runs server-side, the result is delivered as a download. Works in any modern browser.

Are my files kept after conversion?

Direct conversions through this page (the form above) do not persist files at all — the bytes are parsed in memory and the result returned. Persistence only happens when you use the main viewer's Open in roooute button, and persisted files are deleted within 24 hours.

What is the maximum KMZ file size?

50 MB per file.

Does the converter preserve attribute properties?

Yes — feature properties round-trip through the canonical GeoJSON intermediate. Schema differences between source and target formats may force lossy coercions (e.g. shapefile DBF column-name length limits), but rooot viewer applies sensible defaults.
