Lazy loading defers offscreen content — usually images — until the user actually scrolls near it, instead of downloading everything up front. Done right, it cuts initial page weight significantly with no visible trade-off.
Native lazy loading
The loading="lazy" attribute on <img> is supported by every modern browser and needs no JavaScript. The browser decides when an image is close enough to the viewport to start fetching it.
next/image does more
In a Next.js project, next/image combines lazy loading with automatic responsive sizing, modern format conversion (WebP/AVIF), and — critically — reserves the correct space via width/height so the image never causes layout shift when it finally loads in.
What not to lazy-load
The hero image or any above-the-fold content that's visible on first paint should load eagerly (priority in next/image, or no loading="lazy" at all) — lazy-loading it just delays something the user is already looking at.
<Image
src="/images/project-preview.webp"
alt="Project preview"
width={600}
height={400}
loading="lazy"
/>
{/* above the fold — load immediately instead */}
<Image
src="/images/hero.webp"
alt="Hero"
width={1200}
height={630}
priority
/>Reserve `priority`/eager loading for what's visible on first paint, and let everything below the fold lazy-load by default — that split alone covers most real-world performance wins from lazy loading.
