Image Breakdown

Below is a breakdown of how much individual image sizes could be reduced by optimizing them. This analysis was run by loading the page on a simulated mobile device. The page was then scrolled all the way to the bottom, so that lazily-loaded images had a chance to play too. Every image loaded throughout that process was then run through a series of optimizations, after which the numbers were crunched.
