Are my TIFF 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 TIFF to AVIF 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 TIFF to AVIF lose quality?

AVIF 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.

Do I need to install anything to open AVIF files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the AVIF afterwards needs whatever software normally handles AV1 Image File Format on your device.
