This audit is for frontend and CMS QA when responsive images look too large, too blurry or inconsistent across devices. Paste the image markup and review the srcset structure.

What it checks

The report flags missing src fallbacks, missing srcset candidates, width descriptors without sizes, mixed width and density descriptors, duplicate width descriptors and unsorted width candidates.

Scope

The tool checks markup only. It does not download images, inspect dimensions or know the actual rendered slot width.
