Your site's load speed has a direct and measurable impact on user experience, engagement, and conversion rates. Being the largest asset you'll typically find a page, images are often a prime target for optimization.
Below is a breakdown of how much individual images could be reduced by using PicPerf. This analysis was run by loading the page on a simulated mobile device. Every image was then run through a series of optimizations to estimate potential savings.
