Why convert HEIC to AVIF?
Apple made HEIC the default camera format on iPhone because it stores photos at roughly half the size of JPG. Outside the Apple ecosystem support is poor: Windows needs paid extensions and many websites reject HEIC uploads, making it one of the most converted formats on the web.
AVIF is based on the AV1 video codec and reaches even smaller files than WebP at the same visual quality. All modern browsers can display it, but many image editors and older tools cannot open it yet, which is the main reason people convert AVIF to an older format.
