Markdown Preview: what to know

Markdown Preview renders your Markdown as you type, using the open-source marked library with GitHub Flavored Markdown: headings, emphasis, links, images, lists, block quotes and code, plus tables, task lists, strikethrough and autolinked URLs. It's a quick way to check a README, a pull request description or documentation before you publish it.

You can also copy the generated HTML to use in a CMS, an email or a static page. The preview is sanitized with DOMPurify before it's shown, which strips scripts, event handlers and other active content, so Markdown from an unknown source can't run code in the page.

Markdown renderers differ in small ways, especially around nested lists, line breaks and HTML blocks. GitHub, GitLab and most documentation tools follow CommonMark, the specification marked implements, so what you see here matches them closely, but not every extension (such as math or diagrams) is supported.

Popular uses

  • Previewing a README before pushing it
  • Writing pull request and issue descriptions
  • Converting Markdown notes to HTML for a CMS
  • Learning Markdown syntax with instant feedback

Tips for the best result

  • Leave a blank line before a list or a table; some renderers need it to start the block.
  • Use fenced code blocks with a language name (```js) so code gets highlighted on GitHub.
  • See the Markdown cheat sheet in the reference section for every common element.
