AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media. It delivers significantly better compression than JPEG, PNG, and WebP while maintaining excellent quality. Google, Netflix, and Facebook already use AVIF to serve images faster.
Use AVIF for hero images, product photos, and thumbnails. Smaller files mean faster load times and better Core Web Vitals scores for SEO ranking.
