AVIF Image File Format
AVIF is an open and free image file format that can provide over 50% file size savings compared to JPEG and over 30% savings compared to WebP and is supported by most major web browsers. These smaller file sizes reduce storage needs and help pages load faster which improves Largest Contentful Paint (LCP) times and represents how quickly the largest block of content on a webpage has loaded. Using modern codecs to compress images is one of the key techniques to reduce LCP. Lighthouse is a great Chrome developer tool for testing your web site and to see how much savings AVIF would bring.
