Broken Link Checker
- Browser-based
- No signup
Paste HTML or fetch a page URL, extract internal and external links, then test HTTP status codes from your browser. Cross-origin sites may block some checks.
100% Client-Side
Your data never leaves your computer.
How to use this tool
1. Enter the page URL or paste HTML. 2. Run the checker to extract and test links (up to 20 unique URLs). 3. Review broken links with 4xx/5xx status or network errors. 4. Fix or remove dead links before publishing.
Worked example
Example: a footer with an old /pricing link returning 404 appears in the broken links table for a quick fix.
When to use this
- Auditing a page footer before launch.
- Checking migrated blog posts for stale outbound links.
- Validating partner links on a resource page.
- Quick QA on HTML exported from a CMS.
Common examples
- Blog post HTML → flags `/old-pricing` returning 404 in the footer.
- Resource page with 15 outbound links → surfaces two 403 partner URLs blocked to bots.
- Post-migration homepage → confirms `/docs/getting-started` redirects but `/docs/api` is 404.
- Email newsletter archive paste → finds `http://` mixed-content links that fail on HTTPS site.
- Affiliate page QA → catches truncated URL missing trailing slash before publish.
- Internal wiki export → lists broken image `src` paths still pointing at retired CDN host.

How it works
Extract links from HTML or a fetched page, then send HEAD requests to check HTTP status codes. Broken or unreachable links are listed in a results table.
Limitations
Checks up to 20 unique URLs per run. Cross-origin pages may block HEAD requests from the browser (CORS), so paste HTML when live fetch fails. Status codes reflect what your browser can reach—not a server-side crawl.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.
Important notice
Link checks run from your browser and may be blocked by CORS or rate limits. Only the first 20 unique URLs are tested per run.
