What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple text formatting conventions — asterisks for bold/italic, hashes for headings, dashes for lists — that are easy to read in plain text and convert cleanly to HTML. It's become the de facto writing format for technical documentation, README files, static site generators, and developer communication.
Markdown is used by GitHub (README.md, issues, PRs), Stack Overflow, Reddit, Discord, Notion, Obsidian, Jekyll, Hugo, Docusaurus, and countless other platforms. Learning Markdown syntax is one of the highest-leverage skills for any developer.

Frequently Asked Questions
What Markdown flavour does this converter use?▼
This tool uses the marked.js library which implements the CommonMark specification plus GitHub Flavored Markdown (GFM) extensions including tables, strikethrough, and task lists.
Does it support fenced code blocks with syntax highlighting?▼
Yes, fenced code blocks (```language) are converted to <pre><code class="language-..."> elements. You can add a syntax highlighting library like highlight.js or Prism to your project to colorize the output.
What is the difference between Markdown and MDX?▼
MDX is Markdown + JSX — it lets you embed React components inside Markdown files. Standard Markdown only produces HTML. This tool converts standard Markdown to HTML.
Can I use this for email newsletters?▼
Yes. Write content in Markdown for speed, then copy the HTML output to paste into your email builder. Note that email clients have limited CSS support, so complex styling may need adjustment.
Is the conversion lossless?▼
Yes — all semantic content is preserved. Standard Markdown converts deterministically to HTML. Headings become <h1>–<h6>, bold becomes <strong>, italic becomes <em>, and so on.
