Frequently Asked Questions
How does link checking work?
The tool parses your Markdown document to extract all links, then validates each link format and syntax. It checks for common issues like malformed URLs, missing fragments, and invalid reference-style links.
Does it check external URLs?
The tool validates the format and syntax of all links. For external URLs, it performs format validation. Live HTTP checking depends on browser security policies and CORS restrictions.
Is the Markdown Link Checker free to use?
Yes, the Markdown Link Checker is completely free to use. There are no hidden charges, subscriptions, or limitations.
Is my data safe when using this tool?
Absolutely. All processing happens locally in your browser. No data is uploaded to any server, ensuring your information remains completely private and secure.
Can I copy all extracted links at once?
Yes, the Copy All Links button copies every extracted URL to your clipboard, one per line. This makes it easy to paste the URLs into other tools for further analysis or archiving.
