The Markdown to HTML converter turns lightly-marked-up text into ready-to-use HTML code. Markdown is a simple markup language that replaces bulky tags with plain symbols: "#" for headings, "*" or "_" for emphasis, "-" for lists, ">" for quotes, backticks for code, and square/round brackets for links.

This is useful whenever text is written in Markdown — a README on GitHub, notes, or articles in editors like Obsidian or Notion — but needs to go somewhere that expects HTML: an email, a CMS, a website. Instead of manually adding tags, you get clean HTML in a second.

Conversion happens right in your browser (via the marked library), so the text never leaves your device. Paste Markdown on the left and the HTML appears instantly — just copy the result.

Frequently asked questions

CommonMark plus GitHub Flavored Markdown (GFM) through the marked library. That means tables, fenced code blocks (```), and task lists (- [x]) all work.
Sanitization is off by default in marked. If you paste someone else's Markdown containing an embedded <script>, it will end up in the HTML. We show it here as a preview for your own content only — use dompurify if you plan to publish the output publicly.
No — footnotes are a Pandoc extension, and formulas need MathJax or KaTeX. This tool covers base GFM only.
