Convert still AVIF images to WebP

Choose WebP for a workflow that requires WebP files. Adjust quality and maximum width, then compare the original and converted previews. Transparency is retained, but a smaller file is not guaranteed.

Animated AVIF is rejected. Re-encoding may change image detail; keep the original file when fidelity matters.
