Description

Scans every image on the rendered page (SPAs included) and flags the issues that hurt accessibility and Core Web Vitals: missing or empty alt text, oversized images (intrinsic size far larger than displayed), missing lazy-loading, and dated non-modern formats (JPG/PNG/GIF instead of WebP/AVIF). A clear table shows real dimensions and color-coded tags. 100% offline, zero telemetry.

Features

  • Detects missing alt (error) and empty alt (warning) on every <img>
  • Flags oversized images: intrinsic > rendered × 1.5
  • Checks for missing lazy-loading (loading="lazy")
  • Spots dated formats (JPG/PNG/GIF) from extension or data-URI vs WebP/AVIF/SVG
  • Reads real rendered dimensions and the actual source (currentSrc/srcset)
  • Severity-sorted table with aggregated counts per issue type
  • 100% offline: no data leaves the browser, zero telemetry

Privacy
