About Converting KMZ to KML
KMZ is simply a KML file zipped together with any images, icons or overlays it references. It is the format Google Earth exports by default because it keeps a whole annotated map in one portable file. When you need to move away from KMZ, the usual reason is simple: must be unzipped before the geometry can be edited as text.
Converting your KMZ map file to KML solves that. KML is the XML format Google Earth introduced for describing points, paths, polygons and overlays on a map. It became an Open Geospatial Consortium standard in 2008 and is now read by most mapping software. In practice you gain native to google earth and google maps and carries styling, labels and descriptions alongside geometry. PrivConvert runs the whole KMZ-to-KML conversion in server memory and deletes your file the instant the KML is ready — nothing is stored, logged or reused.
When this conversion helps
- You need native to Google Earth and Google Maps
- You need carries styling, labels and descriptions alongside geometry
- You need plain XML, so readable and editable by hand
- Sharing a KMZ map file with someone whose software expects KML
Tips for best results
- After converting, open the KML and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several KMZ files at once; each is processed privately and deleted immediately.
