AVIF and WebP explained
What is a AVIF file?
AVIF is a next generation image format based on the AV1 video codec. It offers excellent compression and quality, often beating WebP and JPG, and is increasingly supported across modern browsers.
What is a WebP file?
WebP is a modern image format from Google that delivers superior compression for both lossy and lossless images. WebP files are typically 25 to 35 percent smaller than equivalent JPG or PNG files.
