Everything is a URL parameter

There is nothing to install and nothing to configure per image. Append the parameters you want and Sizy renders that version on the first request.

const url = "https://sizy.io/your-bucket/photos/beach.jpg

Real-time Transformations

Transform images instantly with simple URL parameters. No waiting, no complexity.

Global Delivery

Rendered images live in globally replicated object storage and are served from close to whoever asked for them.

Usage You Can See

The dashboard breaks transforms and deliveries down by month and by bucket, so a bill is never a surprise.
