ShortPixel offers 2 plugins for image optimization, ShortPixel Image Optimizer (SPIO) and ShortPixel Adaptive Images (SPAI).
ShortPixel Image Optimizer focuses on optimizing the physical image files stored on your server. It operates locally, optimizing the existing images and replacing them with their compressed versions.
ShortPixel Adaptive Images, on the other hand, downloads your images, optimizes them, stores them in ShortPixel’s CDN and dynamically replaces the image URLs when your web pages are loaded.

Now, regarding FastPixel, it’s a comprehensive website accelerator that offers broader functionalities beyond image optimization. Similar to SPAI, it serves next-gen optimized images from a CDN, but it also includes additional features like page optimization, caching, minification of HTML/CSS/JS, critical CSS rendering, and others.
FastPixel provides an all-in-one, integrated plugin that goes beyond just image optimization, catering to various aspects of website performance enhancement.
Ultimately, the choice between these options depends on your specific needs and the depth of optimization and performance enhancement you require for your website.
The FastPixel plugin uses ShortPixel image optimization technology for all the image-related aspects of the website acceleration offered by FastPixel.
