# Overview

[**Pixboost**](https://pixboost.com/) is an Image CDN Cloud Service that delivers images end to end for your website or application.

The service works end-2-end and includes 2 main components:

* API - Collection of HTTP endpoints that optimising and transform images
* CDN - Content Delivery Network that stores optimised images in the closest to the user location

Once an image has been processed, it's cached on CDN, increasing the speed at which images can be retrieved on subsequent requests.
