Are my KMZ files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting KMZ to KML free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting KMZ to KML lose quality?

No. KML stores the same content without discarding anything, so the result is identical in quality to the original. Positions, elevation and timestamps are carried across. Sensor streams, styling and embedded imagery are not.

Do I need to install anything to open KML files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the KML afterwards needs whatever software normally handles Keyhole Markup Language on your device.
