Images are by far the greatest bottleneck to performance on the web, and with the average web page size now about 2.5MB large—images taking up 65% of that—we need to tame the beast. Running images through a compression program like ImageOptim is a good first step, but what else can we do?
In this engaging talk recorded live at An Event Apart Denver 2017, Una Kravets surveys new image formats and dives deeply into image rendering and performance optimization techniques, demonstrating practical approaches to making your web projects noticeably faster.
