Broken Link Checker
Extract absolute http(s) links from pasted HTML only
About this tool
Find broken links in pasted HTML with client-side extraction. Free. Broken Link Checker runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Broken Link Checker is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
