Por que converter KMZ para GEOJSON?
GeoJSON is the expected input format for web mapping libraries such as Leaflet and Mapbox, and for many web APIs. Converting KMZ data to .geojson makes it directly usable in browser-based maps and modern GIS workflows without requiring a desktop viewer.
Como converter KMZ para GEOJSON
QGIS OPEN-SOURCE
Add the .kmz as a vector layer, right-click it in the Layers panel, and choose Export > Save Features As with format set to GeoJSON.
ogr2ogr (GDAL) OPEN-SOURCE
Run ogr2ogr -f GeoJSON out.geojson in.kmz. Use ogrinfo in.kmz to list layers first if the file contains multiple folders.

- Placemarks, lines, and polygons with names and description text transfer correctly; KML styling (icon colors, line widths, fills) has no GeoJSON equivalent and is dropped.
- GeoJSON is always WGS 84 (EPSG:4326), which matches KMZ - no reprojection is needed.
- GeoJSON is plain text and typically larger than a compressed
.kmz; for large datasets consider gzip-compressed GeoJSON or FlatGeobuf for web delivery.
