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.
HTTP2 puts a powerful tool at our disposal to address these issues for image loading. Tobias Baldauf explains how to use HTTP2’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 HTTP2’s multiplexing in depth and demonstrates how to leverage it to address image loading. Following Tobias' unique research, you’ll learn how to take granular control of the encoding process for progressive images to improve both performance and users’ emotional response time to page visuals.
