Introduction

A CMS and CDN usually automatically compress their images when uploaded.  However, you can further optimise an image before upload.  This will include removing the metadata, removing the complexity in the image, removing colours and blurring backgrounds etc.  The primary goal here is to reduce the file size to as small as possible.
