Check Markdown links for empty URLs, duplicates, image alt problems, anchor issues, and internal or external link structure in one report.
Markdown Link Checker produces a cleaned output plus a practical quality report. Use the score, issue counts, and summary to decide whether the text is ready to send, post, or publish.
This tool does not send messages, crawl the web, or verify remote URLs. It checks the text structure available in the pasted input.
Paste a sample into Markdown Link Checker, choose a mode, and compare the original text with the processed output in the dark result card.
The tool uses deterministic browser-side text rules. It counts visible patterns such as links, headings, lists, code fences, footnotes, tasks, and paragraph breaks depending on the page.
Remote link status, private platform rendering rules, and server-side Markdown extensions may differ from the local analysis.
Paste the relevant text into Markdown Link Checker, choose the options that match your goal, and run the tool. Review the output and metrics to find broken markdown links before copying or downloading the result.
