Image SEO & Alt Text Auditor
Audit image alt attributes, explicit dimensions for CLS prevention, lazy loading, and modern format usage.
How It Works
Audit images on web pages or pasted HTML markup. Identifies missing alt tags (WCAG and SEO errors), evaluates decorative empty alts, checks for explicit width/height to eliminate layout shifts, and flags legacy file formats.
Privacy & Processing
Runs locally in your browser · Live URLs fetched via server inspection proxy. Unlike ad-supported directories, there are no third-party trackers, promotional popups, or artificial download delays.
