AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec. It offers the best compression available today - up to 50% smaller than JPG and 20% smaller than WebP at the same quality.
Is AVIF supported in browsers?
AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16+. This covers most modern browsers, but some older browsers may not support it. Consider providing fallbacks for maximum compatibility.
How does AVIF compare to WebP?
AVIF typically achieves 20% better compression than WebP at equivalent quality. However, AVIF encoding is slower and browser support is not quite as universal. Both are excellent modern formats.
Are my files uploaded anywhere?
