Images are quickly becoming one of the most critical factors for web performance. On one hand, users are demanding more visual websites, driving an increase in the number of images on a page and making background images cool again. On the other hand, technology trends such as Retina displays and RWD are making it much harder to choose the right image to download at any given time, avoiding the download of excess bytes.
In this talk, I go over what you can do to maximize the impact of every image byte. I explain the concept of Image Compression, understand how it applies to different image formats, and show the tools and techniques you should use to communicate the best visuals with the fewest bytes. Lastly, I show how to combine image compression and Retina displays, and discuss some newer image formats and how you can take advantage of them today
