How it works

What does this tool check?

It fetches the page HTML, extracts all image URLs from <img> and <source> tags, then checks each image for format, file size, dimensions, and lazy loading attributes.

Why does format matter?

Modern formats like WebP and AVIF compress images 25–70% smaller than JPEG or PNG with equivalent visual quality, directly improving page load speed and Core Web Vitals scores.

Why are some images missing?

Images loaded dynamically via JavaScript are not detected by this tool, as it only analyzes the static HTML. Use browser DevTools for a complete inventory.

Is my data private?

Everything runs directly in your browser. The page HTML is fetched client-side via a CORS proxy and is never stored or logged on our servers.
