Launch GeoEditor for KML / KMZ to GeoParquet
Instant hardware-accelerated 3D viewer. No installation or account required.
Why Engineers Choose GeoEditor for KML / KMZ to GeoParquet
10x-50x Storage Reduction
Compress verbose XML-based KML placemarks and coordinates into Apache Parquet snappy-compressed binary columns.
3D Elevation & Placemarks
Preserve Z-coordinates, ground overlays, and custom placemark styling in a modern WebGL 3D environment.
DuckDB-Wasm Ready
The resulting GeoParquet file is ready for lightning-fast spatial SQL queries via DuckDB, Sedona, or Athena.
Zero Data Leakage
Convert sensitive survey tracks and infrastructure boundaries locally without third-party cloud converter risks.

Frequently Asked Questions About KML / KMZ to GeoParquet
Why should I convert KML to GeoParquet?+
KML is an XML format designed for display, making it inefficient for large analytics. GeoParquet is a columnar binary standard that is up to 50x smaller and executes SQL queries 100x faster in DuckDB or cloud engines.
Can GeoEditor open KMZ files as well?+
Yes. GeoEditor unpacks KMZ archives in-memory and parses the internal doc.kml file along with associated icons and overlays.
Will Z-coordinates (altitude) be preserved?+
Yes. 3D geometry coordinates are converted into 3D WKB geometries, preserving accurate terrain heights.
