Web performance without the busywork.

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

Unoptimized images can hurt your site's ability to reach and serve your audience. PicPerf provides lossless image compression for websites that maintains visual quality throughout.

• Every milliscond matters to your users.

  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, it's critical to optimize images for website delivery 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 how long it takes to load the bulk of your page's content (LCP) and how much shift/jank occurs as it loads (CLS).

The primary culprits of slow, over-sized images on the web.

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. When you optimize webp images with PicPerf, you get significant file size reductions.
  
  Every visitor will get an extremely light, optimized image ready for the modern web.

• Grossly oversized images.

  An alarming number of images are simply too large for the space they occupy, forcing every user to download far more data than necessary.
  
  PicPerf provides multiple tools for reining in image sizes, including automated, behind-the-scenes resizing that helps you resize images without quality loss, ensuring your images load faster while maintaining visual quality.
  
  This means your visitors won't be asked to download needlessly large images.

Immediate, measurable results.

Performance tooling will take notice right after enabling PicPerf. Image compression for websites happens automatically with this website image optimization tool, and you'll never have to see Google's PageSpeed Insights tool tell you to serve your images in next-gen formats again.

Let's put the impact in perspective.

Here's what happens when you optimize images for web performance with 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.

Two options for using PicPerf.

Prefer zero image-URL work at all? Turbulence optimizes every page — images included — with a DNS change instead.

Resize any image with simple URL parameters.

Forget about manually resizing images to fit a certain spot on your site. PicPerf will automatically resize images, an essential part of website image optimization that helps maintain visual quality.

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, helping to resize images without quality loss for faster delivery.
• The lighter, resized images are aggressively cached and served for future users.

Wire it all up to your own custom domain.

Whether it's for white-labeling, branding, or some inexpressible personal satisfaction, using your own domain for serving optimized images is easy and provides lossless image compression for website performance. Setup takes just a couple minutes.
