Performance
A lot of CMSs have image transformations built in. An image transformation encompasses everything for that image including responsive sizes, cropping, resizing, and face detection from the original. This is great for small sets of images, but transformations quickly get out of hand the more images there are on a site. For example, the homepage of the National Park Foundation has a minimum of 96 image transformations.
Processing all of those image transformations uses a lot of server resources. Imgix saves the images and delivers them through their CDN. The imgix image CDN has an average of 0.15 milliseconds return on requests which enables images to load as quickly as possible. The CDN also caches the images on CDN edge nodes making them immediately available for future requests.
Flexibility
Imgix is flexible enough to work with almost any site structure; including WordPress, Craft CMS, Shopify, React, Ruby on Rails, Python, and more (see the full list). So, whether a site is a WordPress site or a Rails application, imgix fits right into the ecosystem. And, even better: you don’t have to rebuild your web app or website to gain the benefits of image performance, which can save you a lot of time and money.
Setting up imgix on an existing website is easy. Imgix can connect to existing asset storage sources like AWS, Azure, or a web folder on the same domain. Once the image source is set up, a developer can start passing parameters to the API.
