KML to KMZ Converter
Package a raw KML file, including a drone flight plan or waypoint set, into a single zipped KMZ that is easier to share. Runs locally, no upload.
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 KML to KMZ
Drone pilots and mapping teams often end up with a bare KML file that references separate icons or images. Zipping it into KMZ bundles everything into one file, which is friendlier to share and less likely to break when it is opened somewhere else.
Curious how the conversion itself works with nothing ever uploaded? Read how TrailConvert works.
