What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting conventions (like # for headings and ** for bold) that convert cleanly to HTML. Markdown is used in GitHub READMEs, documentation sites, blog platforms, and note-taking apps.

Supported Markdown syntax

# Headingh1–h4
**bold**<strong>
*italic*<em>
`code`<code>

Frequently asked questions

Why doesn't it support tables or task lists?

Tables, task lists, footnotes, and strikethrough are part of extended Markdown dialects (GitHub Flavored Markdown, CommonMark extensions). This tool supports core Markdown only. For full GFM support, use a library like marked.js.

Is the output safe to embed in a webpage?

HTML special characters in your Markdown are escaped before conversion, preventing most XSS vectors. However, always sanitize user-generated HTML before inserting it into a live page.
