Getting Started

Welcome to sizy.io, your go-to service for on-the-fly image resizing and delivery via CDN.

What is sizy.io?

sizy.io simplifies how you handle images by:

Under the hood, sizy.io uses Sharp.js for fast and efficient image transformations. For advanced image manipulation details, be sure to check out their documentation.

How Does It Work?

  1. You create (or connect) a storage bucket in sizy.io to store your source images.
  2. You replace your existing image URLs with sizy.io links (with parameters) in your website or app.
  3. Whenever a user visits a page that includes these images, sizy.io:
    • Fetches or caches the source image
    • Applies the requested transformations
    • Delivers the result via a CDN

The process is nearly seamless once you’ve set up your bucket and updated your image URLs.

Note: If you're unfamiliar with image transformations and the parameters you can specify, be sure to read the All Parameters page after this one.
