About Markdown Converter
Markdown has become the de facto standard for writing technical documentation, README files, blog posts, and knowledge base articles. Its lightweight syntax — asterisks for bold, hashes for headings, backticks for code — produces clean HTML without the overhead of a rich text editor. But to see exactly how Markdown will render, you need a live preview that processes it in real time.
Our Markdown Converter provides a split-pane editor where you write on the left and see the rendered HTML preview on the right, updating as you type. It supports the full GitHub Flavored Markdown (GFM) specification including tables, task lists, strikethrough text, fenced code blocks with syntax highlighting, and footnotes. The rendered output closely matches how your content will look on GitHub, Notion, and most modern documentation platforms.
The "Export HTML" feature generates a standalone HTML document with inline CSS for the Markdown styles, making it portable for use in email campaigns, static HTML pages, or CMS systems that accept raw HTML. The exported HTML is clean, semantic, and works without any external stylesheets or JavaScript.

- ✓Use task lists (- [x] Done item) for Markdown checklists that render as checkboxes
