Broken Link Checker — Check Dead Links from URL List or HTML

Quickly Detect Broken Links

Broken links frustrate users and damage SEO. Use this free broken link checker to instantly validate any list of URLs or embedded HTML links. Whether you’re auditing a website, cleaning up a blog post, or testing HTML content — this tool makes it fast and easy.

Two Input Modes: URL List or HTML Source

You can paste a list of links (one per line) or paste an entire HTML page. The tool automatically extracts links in either mode. No need to copy individual <a href="..."> manually — just drop your content and go.

Real-Time Status Checks

• 🔎 HTTP status lookup via HEAD requests
• ✅ Pass/fail detection for each link
• 📋 Copyable result table with status and labels
• ⚠️ "Opaque (CORS)" status for privacy-blocked URLs

You'll see color-coded results showing which links are live, which returned an error, and which couldn’t be validated due to browser CORS restrictions.

Use Cases

• 🧑‍💻 Check URLs before publishing web content
• 📄 Audit blog posts or markdown docs for dead links
• 🧼 Clean up outdated references in old HTML files
• 🔍 SEO fixups for anchor link health
• 🧪 QA and UAT test link health before deployments

2. Paste links (one per line) or raw HTML code
3. Click "Check Links"
4. See HTTP status, result icon, and copy any value
