Free Markdown editor with live HTML preview
Write in Markdown, see the HTML render as you type. Supports GitHub Flavored Markdown — tables, task lists, strikethrough, code blocks.
Sanitized with DOMPurify so pasted HTML can't execute scripts. Export as clean HTML or download as .md. Nothing uploaded.
Frequently asked
What is GFM?
GitHub Flavored Markdown — a superset of CommonMark adding tables, task lists - [ ], strikethrough, autolinks.
Is my content uploaded?
No. Rendering happens client-side via marked + DOMPurify.
Can I paste raw HTML in the editor?
Yes. HTML passes through DOMPurify — scripts and unsafe attributes are stripped for safety.
Where's syntax highlighting for code blocks?
Not included by default (adds ~50KB). Copy the HTML and pair with a highlighter like Prism or Shiki in your site.
Free forever?
Yes.
