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 be smaller than my PNG? +
Usually much smaller, especially for photos and detailed graphics. Tiny flat-color icons save less, since PNG already handles those well.
