Images are a crucial component of all websites. They evoke emotions and prompt actions. They also form 64% of website data and have the highest correlation to page-load time. While modern image compression techniques can alleviate some of the negative impact of image loading, key web performance metrics such as the Speed Index and Time to Interact suffer due to our need for images.
HTTP/2 puts a powerful tool at our disposal to address these issues for image loading. Tobias Baldauf explains how to use HTTP/2’s superpowers to optimize image delivery, thereby increasing the perceived performance of your page, reducing load times, and driving conversions. Tobias explores the details of HTTP/2’s multiplexing in depth and demonstrates how to leverage it to address image loading. You’ll learn how to take granular control of the encoding process for progressive or interlaced images to improve both performance and users’ emotional response time to page visuals.

You are responsible for web performance, and you need to increase the perceived performance of your page, reduce load times, and drive conversions.
