Slow images are costing you visitors and revenue.

Every second of load time costs conversions. Research shows a 1-second delay reduces conversions by 7%. Your images could be 51% smaller — that's a meaningful speed gain ready for the taking.

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.

"PicPerf is one of the best services I've used. You just add a prefix to your asset URLs, and then it just works."

Eric Barnes / Laravel News

"PicPerf optimizes the images for me and automatically uses the best format for the user. What more could you want?"

Jason Beggs / Design to Tailwind
