Google's Core Web Vitals directly impact search rankings, and LCP (Largest Contentful Paint) is often determined by your largest image. Web developers need systematic image optimization — not just one-off compression, but a pipeline that consistently delivers fast-loading, visually sharp images across every page.

Tips for web development

Target LCP under 2.5 seconds — the hero image is usually the LCP element, so compress it aggressively

Convert to WebP with AVIF fallback — WebP saves 25-34% over JPEG, AVIF saves 50%

Implement responsive images with width descriptors (srcset) to serve appropriate sizes per viewport

Use a build-time compression pipeline (Sharp, imagemin) to automate optimization in CI/CD
