KMZ to GeoJSON Converter
Turn a KMZ flight path or waypoint file, the kind most drone planning software exports, into GeoJSON for a web map. Runs entirely in your browser.
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 GeoJSON
Drone flight-planning tools commonly export KMZ, but showing that flight path on a web map means it needs to be GeoJSON first. This unzips the KMZ and rewrites the geometry directly, without the file ever leaving your device.
Curious how the conversion itself works with nothing ever uploaded? Read how TrailConvert works.
