KMZ to KML Converter
Unpack a zipped KMZ file into plain KML so you can read or edit the underlying placemarks and paths directly. Everything happens on your device.
Your files never leave this tab
There is no upload. Files are read by the code already running on this page, processed in memory, and handed straight back to you as a download. This tool has no server that accepts your data and nothing is written to storage.
Want proof? Turn off your Wi-Fi, then convert. It still works, because the work happens on your device.

Why convert KMZ to KML
KMZ is convenient for sharing, but the KML inside it is what most editing tools and scripts actually work with. This unzips it and hands you the raw KML, useful for a quick edit of a flight plan or route someone else sent you.
Curious how the conversion itself works with nothing ever uploaded? Read how TrailConvert works.
