Are my JXL 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 JXL to GIF 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 JXL to GIF lose quality?

GIF is a compressed format, so some data is discarded. At the default setting the difference is not visible; you can raise the quality setting if you need to be certain. Reduced to 256 colours, which is visible on photographs.

Do I need to install anything to open GIF files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the GIF afterwards needs whatever software normally handles Graphics Interchange Format on your device.
