We use ad-blockers as well, you know. We gotta keep those servers running though. Did you know that we publish useful books and run friendly conferences — crafted for pros like yourself? E.g. our upcoming SmashingConf London, dedicated to all things web performance.
Web developers spend their days writing hypertext, but, byte for byte, most of the web is composed of images. It is hard to overstate the effect that images have on the average web page’s performance; faster websites have broader reach and a higher impact. The first and most important thing you can do to improve the performance of your website’s images is figure out how to measure them.
Enter Website Speed Test, a free and drop-dead-simple tool that leverages our (Cloudinary’s) image smarts to let you measure, diagnose and (crucially) communicate about the image performance of any website. Better yet, it’s built on top of, and integrated in, Pat Meenan’s WebPagetest. Interested? Read on!
Four years ago, Jason Grigsby asked a surprisingly difficult question: How do you pick responsive image breakpoints? A year later, he had an answer: Ideally, we’d set responsive image performance budgets to achieve "sensible jumps in file size."
Cloudinary built a tool that implements this idea, and the response from the community was universal: "Great! Now, what else can it do?" Today, we have an answer: art direction!
Images are some of the mostimportantpieces of information on the web, but over the web’s 25-year history, they haven’t been very adaptable at all. Everything about them has been stubbornly fixed: their size, format and crop, all set in stone by a single src.
