What is Link Checker?
A link extractor and checker. It lists every link in a Markdown document and, on request, pings each URL from your browser to flag broken ones.
How it works
Links are parsed from Markdown syntax, then fetched via the browser (subject to CORS — some URLs can't be checked, which is expected).
- Enter your input. Type or paste your input into the field above — the tool responds instantly.
- Review the result. Output updates live as you type. Everything runs entirely in your browser.
- Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
Examples
Auditing a doc's links
Extract every link from a Markdown document and check its format — relative paths, absolute URLs, and in-page anchors.
Common mistakes
Format checking isn't link checking
The tool validates link syntax locally; it doesn't fetch URLs to confirm they resolve.
Frequently asked questions
Why do some links show 'could not check'?
Browsers enforce CORS, so some servers block cross-origin requests. A link that can't be checked isn't necessarily broken — it's a browser security limitation.
