Broken Link Checker
Paste a page's HTML source to flag links with empty hrefs, malformed URLs, or other common problems.
Everything runs locally in your browser — nothing is sent anywhere. This tool checks the HTML you paste in, not a live URL.
This checks the links in your pasted HTML for common problems — it doesn't crawl or fetch each URL to confirm it's live, since that would require sending your links to a server.
Result
Paste HTML on the left to scan its links.
How to use it
- 1View a page's source (Ctrl/Cmd+U) and copy it.
- 2Paste it into the box.
- 3Review any flagged links.
Is my file uploaded?
No — the check happens locally in your browser on the HTML you paste in. It doesn't fetch or crawl any URLs.
FAQ
- Does this confirm links actually load (return a 200 status)?
- No — it only checks the link syntax in your pasted HTML for common problems. Confirming a link is genuinely live requires fetching it, which this browser-based tool doesn't do.
