How to Preview Markdown

Markdown Preview

When to Preview Markdown

Draft README files, documentation, blog posts, or release notes and see the rendered HTML instantly. Live preview helps catch formatting issues, broken lists, and heading hierarchy mistakes before publishing to GitHub or a CMS.

Security

Raw HTML embedded in Markdown source is stripped during rendering. Script tags and unsafe attributes are removed so preview output cannot execute code in your browser — paste untrusted Markdown safely for inspection.

Supported Syntax

GitHub Flavored Markdown is supported — headings, lists, links, emphasis, code fences, blockquotes, and tables render in the preview panel as you type without clicking Run.

Frequently asked questions

Is raw HTML allowed in Markdown?

Raw HTML in source is sanitized and stripped for safety. Use standard Markdown syntax instead.

Does preview match GitHub exactly?

Rendering is close to GFM but may differ in edge cases like nested lists or custom HTML.
