How Focal works

Your images stay in your bucket or on your server. When a browser asks for a size, Focal fetches the original and makes that size. Focal caches the result at the edge. The next request for that size comes from the cache. You change the size by changing the URL.

How Focal works Originals stay in your bucket (S3, GCS or R2) or on your own server. Focal is one server that fetches the original, transforms it, caches the result at the edge and delivers it.
