Frequently asked
Why does the first conversion take a moment? +
The AVIF encoder is about 1 to 2 MB of WebAssembly and downloads the first time you use it. After that it's cached and conversions are fast.
Will AVIF really be smaller than WebP? +
Often yes, especially on photographs. The gain is smaller than it is against JPG, but at matched quality AVIF usually edges out WebP.
