Developers, SEO teams, and site owners need a fast view of the image formats a page actually ships before investing in a deeper performance audit.
Capabilities
WebImgScan discovers image URLs, reports the total count, groups formats such as WebP, SVG, JPEG, PNG, and GIF, and exposes the full URL list. Its “green site” signal marks pages whose discovered images use modern efficient formats; otherwise it highlights modernization work.
How it works
Constraints
Format distribution is a useful first signal, not a complete performance score. File size, dimensions, responsive sources, compression, caching, and rendering behavior still require deeper inspection.
