GPX to KMZ Converter

Package a Strava or Garmin GPX export as a zipped KMZ file, ready to share or open directly in Google Earth. Runs locally, nothing is uploaded.

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 GPX to KMZ

KMZ is just a zipped KML, which makes it the easiest format to hand someone who just wants to double-click a route and see it in Google Earth. Cyclists exporting from Garmin or Strava usually reach for this when sharing a route rather than a device file.
