Optimize Images for Website

Web image optimization and Core Web Vitals

Heavy images are one of the biggest drags on real-world performance. Google’s Core Web Vitals—especially Largest Contentful Paint (LCP)—directly reward pages whose hero and in-content images decode quickly. Compressing to WebP at sensible quality (often around 80%) and capping width (for example 1920px for full-bleed desktop heroes) removes wasted pixels most users never see on screen.

CLS, responsive images, and delivery

Cumulative Layout Shift (CLS) improves when you reserve space for media and avoid loading oversized bitmaps that get scaled down in CSS alone. Pair optimized files with responsive srcset markup or your framework’s image component, lazy-load below-the-fold assets, and serve them over HTTP/2 or HTTP/3 through a CDN so repeat visits hit the cache. WebP’s smaller payloads make each of those layers more effective.

Why WebP for the web

WebP typically beats JPEG and PNG on byte size for the same visual quality, which shortens time-to-interactive and reduces hosting egress. Use this tool to batch-optimize masters before upload—dimensions and format applied locally, with no cloud processing of your originals.
