Dead links (also called broken links) are hyperlinks that no longer work or point to non-existent resources. They result in 404 errors, connection failures, or redirect loops. This tool scans URLs in your content and checks their status, helping you find and fix broken links.

Paste your content containing URLs (HTML, markdown, or plain text with URLs) in the input area and click Scan to check all links. The tool will extract URLs, check each one, and display results with status codes (200 OK, 404 Not Found, etc.). Results categorize links as valid, broken, or problematic. Click Copy to export results, or Clear to scan again. All processing happens locally in your browser.

Dead links hurt user experience, damage SEO rankings, and reduce site credibility. Search engines penalize sites with many broken links. Regular link checking is essential for maintaining content quality, especially for older pages or external references.
