Alt Inspector – Alt-Text Overlay is a free Chrome extension designed to enhance web accessibility and SEO by displaying alt texts for images on web pages. This tool overlays alt text directly on images, making it easier to identify missing attributes and generate detailed reports in CSV and PDF formats. The user-friendly widget lists image sources and sizes, providing a clear overview of assets on the page.

Key features include the ability to filter and search for images, highlighting those without alt text, and quick toggling of overlays using keyboard shortcuts. The tool supports various image formats, including SVG, and ensures no data is collected or stored, running entirely within the user's browser. Alt Inspector is ideal for SEO teams, content editors, and web developers looking to improve content quality and accessibility.
