On Tour @ #perfnow 3/6 with Kornel Lesiński

This interview is part of our six-part series On Tour @ #perfnow. At the beginning of November, we attended a new conference in Amsterdam called performance.now(). performance.now() is put together by no-one less than Steve Souders and Tim Kadlec, two well known experts in the performance circus. And they teamed up with the people running the CSS Day. What they put together was nothing short of amazing. They had 16 of the most talented speakers flying in from all over the world, and we got the opportunity to interview a few of them! Kornel Lesiński: Optimizing Images for the Web Most developers have used Kornel’s work already via tools like mozjpeg, PNGquant and most famously ImageOptim. We speak about the present and the future of image formats. For example we discuss how WebP changed the web and what problems come with it. One of the most interesting formats for the future seem to be AV1 which can be used partially today already.
