PNG to AVIF: what carries over and what does not

PNG carries 16 bits per channel and AVIF carries 12, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 12-bit format only at the very end. PNG stores pixels without compression loss and AVIF does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.
