Frequently asked questions

How does AVIF compression compare to HEIC?
HEIC and AVIF use similar underlying technology (HEVC and AV1 respectively - both derived from video codecs). AVIF is often comparable to or slightly better than HEIC in compression, but AVIF is designed for web use with broad browser support.
Is AVIF widely supported enough to use in production?
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+, covering about 90%+ of web users globally. Use a <picture> element with a JPG or WebP fallback to cover all users.
Why convert HEIC to AVIF instead of JPG or WebP?
AVIF gives the smallest file sizes of any web-compatible format - 40-60% smaller than JPG and 20-30% smaller than WebP. For high-traffic web apps or bandwidth-constrained environments, AVIF makes a meaningful performance difference.
