Review website URLs and identify entries that need further checking. Use the tool to organize a list of links before testing them with a crawler or HTTP checker.
Broken Link Checker
Check a list of URLs for reachable HTTP responses. Some websites block browser-based checks.

Insights / Tips
- Checks are made from your browser and may be blocked by CORS or remote-site security rules.
- A failed browser request does not always mean the URL is broken.
- For reliable site-wide scans, use a server-side crawler or SEO audit tool.
What this tool can do
- Bulk URL input: paste one URL per line.
- URL format checks: identify entries that are not valid absolute HTTP or HTTPS URLs.
- Review-ready list: organize URLs that require a more reliable status check.
- Clear limitations: distinguish invalid URL formats from remote links that have not been verified.
How to use the broken link checker
- Paste the URLs you want to review, one per line.
- Click Check Links.
- Review invalid URL formats and the list of links requiring further testing.
- For confirmed HTTP status codes, run the URLs through a server-side crawler or link-checking service.
Important notes
- A browser-only tool cannot reliably confirm the status of arbitrary remote URLs because of CORS and site security rules.
- A failed browser request does not always mean a link is broken.
- For site-wide checks, crawl internal links and review 404, 5xx, redirect, and timeout results.
Frequently asked questions
What is a broken link?
A broken link points to a resource that cannot be reached as intended, often returning a 404 or another error.
Can this tool verify every link?
No. Browser security restrictions can block requests to other domains. Use a server-side checker for confirmed status codes.
How often should I check links?
Review important pages after redesigns, migrations, URL changes, and regular content updates.
Should I remove every redirected link?
Not necessarily. Update links to point directly to the final relevant URL when practical, but preserve useful redirects.
