What changes when you convert VTF to AVIF
VTF and AVIF both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it.
