How can you provide stunning photos and graphics without compromising website or app performance? Six of Akamai’s foremost image experts teamed up with O’Reilly Media to answer that question. The result is High Performance Images, a book providing useful tips, tricks, and practical theory to help developers deliver powerful images on any website or app. For more on High Performance Images watch the video below, or download the e-book now.
Very readable, despite lots of "in the weeds" details about what goes into various image formats and what makes them tick. I'd love to see an updated version (this is five years old at the time of writing this review), that's expanded with some opinionated approaches for front-end developers: "lazy load if you can" and "size images appropriately" aren't exactly major revelations for anybody at this point.
Really well organized and talked about a lot of things I would consider to be previous unknown unknowns. Even though I know I didn't absorb everything I feel like I absorbed enough to convert the unknown-unknowns to at least known-unknowns and there were definitely things that became known-knowns. I was a little hesitant going into this book expecting it to feel fairly dated since it was published in 2016 and I read it in 2024 but I really think it has held up so far except for a few details. I was really pleased seeing that it covered WebP because I know that is a newer format.
