AVIF, JXL, DSSIM, DPR, CLS, LQIP, srcset, loading=lazy, fetchpriority ... it's not easy to embed a simple photo on a website in a performant way. In this talk, we'll take an active look together at what a real-world usable workflow for high performance images can look like.
From image IDs, cache-keys and metadata for CLS over file formats, automated lossy compression and the picture element, loading strategies and UX we'll look at all important components and their complex interaction - always focused on web performance & real-world maintainability.
