Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.
Every image is checked for alt text. Missing alt text means screen readers cannot describe the image to users, making the content inaccessible to people with visual impairments.
For finding images with broken URLs, try the Dead Image Detector.
Links with generic text like 'click here', 'read more', or 'this link' are flagged. Screen reader users often navigate by link list, where 'click here' gives no context about the destination. Descriptive link text improves usability for everyone.
Heading level jumps (e.g., H2 followed by H4) are flagged because screen readers announce heading levels to help users navigate. Skipping levels creates a confusing document structure.
For detailed heading hierarchy analysis, see the Structure Validator.
Tables without a header separator row are flagged. In HTML, tables need <th> elements so assistive technology can associate data cells with their column headers. The Markdown header separator row generates these.
For broader SEO analysis including heading and image checks, use the SEO Checker.
