Effortlessly make your website's images light, modern, and fast.

Light, fast images matter for SEO, Core Web Vitals, and conversion rates.

If left neglected, unoptimized images can have a real impact on your site's ability to reach and serve your audience.

• When it comes to page performance, every milliscond matters.

  People are shockingly good picking up on slowness, with research even suggesting that, in some cases, even 10ms can be perceived by the human brain. As one of the most expensive assets on your website, images are critical to optimize well, so that latency in viewing a page's content is minimized.

• Search engines care about your image performance.

  Google uses its Core Web Vital as one of the many factors in determining page rank and overall user experience. Images that perform poorly can threaten these key metrics, including long it takes to load the bulk of your page's content (LCP) and how much shift/jank occurs as it loads (CLS).

Ain't nobody got time for slow, heavy images.

Poorly optimized images are pounding the web, and for most people, it feels like too much of a hassle to fix. Specifically, PicPerf addresses two common issues:

• Poor cache headers.

  Many images aren't cached long enough, and even if they are, browsers are forced to revalidate them on every request.
  
  PicPerf makes images locally cacheable for a year and immutable, so they never need to be revalidated. And when they do need to be fetched again, the're available from the best CDN in the world.
  
  This means your visitors won't have to redownload your images every time they visit your site.

• Hefty image formats.

  Modern image formats like WebP and AVIF are widely supported by modern browsers, and offer serious savings in file size. But many sites have yet to take advantage.
  
  PicPerf automatically converts your images to WebP or AVIF (whichever is lighter for the specific image) and only serves it if it's smaller than the original.
  
  Every visitor will get an extremely light, optimized image ready for the modern web.

Immediate, measurable results.

Performance tooling will take notice right after enabling PicPerf. You'll never have to see Google's PageSpeed Insights tool tell you to serve your images in next-gen formats again, and your vistors will get a faster page experience that won't drain their data plan.

Let's put the impact in perspective.

Here's what happens when a large, unoptimized image is run through PicPerf. For illustration purposes, we're simulating the speed you might find on a standard mobile connection. Those with sensitivities to slow websites may want to look away.

• Before: a sloooooow PNG.

  2.4MB, 14 seconds to load. 😱

  

• After: a fast AVIF!

  233KB, just 1.9 seconds to load. ⚡️

  

That's over 90% smaller and 86% faster just by prefixing the URL. Examples like this are more common than you might expect.

It works just by wrapping the images you're using today.

There's no need to move your images anywhere, and the original versions will never be touched. Just tacking on PicPerf's domain makes for a huge difference.

Resize any image with simple URL parameters.

Forget about manually resizing images to fit a certain spot on your site. PicPerf will automatically do it by putting the dimensions directly into the URL.

Automatically resize over-sized images behind the scenes.

Accidentally shipping a 3000px-side image that'll only ever show in a 200px-wide spot is a problem of the past. Here's how it works.

• Behind the scenes, PicPerf periodically measures your site's images, using a virtual browser to determine if they could be scaled down.
• Every eligible image is resized based on how it actually shows up on a large screen.
• The lighter, resized images are aggressively cached and served for future users.
