<b>The one image change that helps Core Web Vitals most</b>

If you do a single thing for performance this week, switch your images to a modern format. Old JPEGs and PNGs are heavy, and heavy images are usually the thing dragging down LCP — Largest Contentful Paint, your biggest visible element.

Modern formats squeeze the same picture into far fewer bytes:
— WebP is typically 25 to 35 percent smaller than JPEG
— AVIF can be 50 percent smaller, with the same visible quality

Think of it like vacuum-packing a sweater — same sweater, half the suitcase.

How to start:
— Export your hero and top images as WebP (every modern tool supports it)
— Use a <code>&lt;picture&gt;</code> tag to offer AVIF, then WebP, then a JPEG fallback
— Compress at quality 80 — eyes can't tell, but bytes can

<b>Try this:</b> Convert just your three heaviest images and recheck. This one's easier than it sounds, and the payoff is immediate.
