Lazy loading images checker
What is a Lazy Loading Images Checker?
The Lazy Loading Images Checker inspects every image on a webpage and reports which ones use the native loading="lazy" attribute versus which ones load eagerly regardless of whether they're visible on screen.
Why Lazy Loading Matters
- Faster initial page load — Deferring off-screen images means the browser spends its early bandwidth on content the user can actually see first.
- Core Web Vitals — Reducing initial payload size can improve metrics like Largest Contentful Paint, a Google ranking factor.
- Don't lazy-load everything — Above-the-fold images (especially the LCP image) should generally NOT be lazy-loaded, since that can delay their appearance and hurt LCP instead of helping it.
