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.
