AVIF quality is on its own scale — around 50% is usually visually excellent. HEIC transparency is preserved (AVIF has a full alpha channel). HEIC decodes natively in Safari 17+; other browsers use a WebAssembly libheif decoder downloaded once from a CDN, and the AVIF encoder is a separate one-time WebAssembly download. Bursts, live photos and animated HEIC use their primary image. Large images can take several seconds each.
