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 CSV 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 CSV lose quality?

KMZ and CSV describe content in fundamentally different ways, so the conversion is a reconstruction rather than a copy. The result is faithful, but not byte-for-byte equivalent. One row per recorded point. Anything the file held beyond position, elevation and time is not in a table.

Do I need to install anything to open CSV files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the CSV afterwards needs whatever software normally handles Comma-Separated Values on your device.
