Full Explanation
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. AVIF offers even better compression than WebP, typically producing files 50% smaller than JPEG at similar quality. AVIF supports high dynamic range (HDR), wide color gamut, and both lossy and lossless compression. Browser support has grown significantly, with Chrome, Firefox, and Safari all supporting AVIF. Due to its superior compression, AVIF is excellent for improving LCP scores. The main drawback is slower encoding times compared to WebP or JPEG. Use AVIF as the primary format with WebP and JPEG fallbacks.
