Broken Link Checker — Find Dead Links & Redirects

Find broken links, dead pages and messy redirects fast with the Broken Link Checker. Feed it a list of URLs or a page to crawl for links, and get a clean report of every link's HTTP status, redirect chain, final URL, content type and errors — exported as JSON, CSV or Excel.

Built for SEO audits, website maintenance, content migrations, link-building QA and pre-launch checks, this tool catches 404s, dead domains and redirect loops before your visitors (or Google) do.

What it does

• 🔗 Check any list of URLs — paste the links you want tested.
• 🕸️ Or scan a whole page — give it a page URL and it extracts and checks every link on it (href and src).
• 🚦 Clear status for each link — HTTP status code, healthy vs broken, and the exact error for failures (404, 500, DNS failure, timeout, connection refused…).
• ↪️ Redirect insight — how many redirects a link goes through and the final destination URL.
• 🎯 Filters — check external links only, or output only the broken ones.
• ⚡ Fast & parallel — adjustable concurrency with a per-URL timeout so slow servers never stall the run.
• 📤 Export anywhere — JSON, CSV or Excel, or straight into Google Sheets or a dashboard.

FAQ

Do I need an account or key? No. Paste your URLs or a page URL and run.

How does it decide a link is broken? Any link that returns a 4xx/5xx status, fails to connect, hits a DNS error, or times out is marked broken. Links returning 2xx/3xx are healthy, with redirects reported separately.

Does it follow redirects? Yes — it follows redirect chains, reports how many hops there were, and records the final URL.

Can I check just the links on one page? Yes — enter a Page URL and it extracts every link on that page and checks them all. Use "External links only" to focus on outbound links.

Can I export to Excel or Google Sheets? Yes — results download as JSON, CSV or Excel and integrate with Sheets and dashboards.
