Are my GPX 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 GPX to TCX 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 GPX to TCX lose quality?

GPX and TCX 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. Positions, elevation and timestamps are carried across. Sensor streams, styling and embedded imagery are not.

Do I need to install anything to open TCX files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the TCX afterwards needs whatever software normally handles Training Center XML on your device.
