What is a Broken Link Checker?
A broken link checker scans a webpage's HTML for all anchor tags, extracts every URL, and then verifies whether each link returns a successful HTTP status. Finding and fixing broken links is essential for SEO and user experience, because dead links frustrate visitors and can harm your search rankings. This tool performs the entire process inside your browser—you just provide the page's source or URL, and it checks each link in the background without any data leaving your machine.
How to Use
- Provide the source by either entering a webpage URL and clicking "Fetch" (if CORS allows) or pasting the full HTML into the textarea.
- Click "Extract Links" to parse all anchor tags, resolve relative URLs, and list the unique links. The link count updates above.
- Click "Check Links" to start verifying each URL. The tool will send a request to each link and display the HTTP status code. The progress bar shows completion.
Frequently Asked Questions
Why do some links show "CORS blocked"?
The browser prevents direct HTTP requests to external sites for security reasons. If the target server does not allow cross‑origin requests, the tool cannot determine the exact status and will show a CORS warning. For same‑origin links or URLs that permit CORS, the checker works perfectly.
Is my data safe?
Absolutely. All link extraction and verification happens directly in your browser. No webpage content or link information is ever uploaded, stored, or logged. Even the fetched HTML is processed locally and never leaves your device.
Does the tool work offline?
You can extract links from pasted HTML without an internet connection. However, checking whether those links are alive requires an active connection because the tool needs to send requests to each URL.
