Markdown → HTML

Escribe o pega Markdown a la izquierda, mira el HTML renderizado a la derecha. Copia el HTML con un clic. Todo sucede en tu navegador — sin subir nada, sin inicio de sesión, sin rastreo.

HTML renderizado

El HTML renderizado aparecerá aquí.

Consejo: las ediciones se aplican en el siguiente fotograma de animación, así que incluso documentos muy largos se mantienen fluidos. Usa Ctrl/⌘+A dentro del editor para seleccionar todo tu Markdown.

La conversión se ejecuta en tu navegador usando marked v15.0.7 (MIT, vendorizado con la página). No se hacen llamadas de red cuando escribes. La vista previa se renderiza en la página a partir de tu propia entrada — así que solo tú puedes afectar a lo que aparece en tu vista previa, pero si pegas Markdown en el que no confías y haces clic en un enlace dentro de la vista previa, ese enlace navegará. No pegues Markdown no confiable.

About this tool

Markdown to HTML converts CommonMark-flavoured Markdown into clean HTML in your browser. The conversion follows the CommonMark 0.30 spec with GitHub-flavoured extensions for tables, task lists, strikethrough, and fenced code blocks with language hints. The output is HTML5 with no inline styles, no classes unless you opt in, and no JavaScript. You can preview the rendered HTML in the right pane and copy either the HTML source or the rendered preview to the clipboard. The converter is bundled into the page; there is no remote fetch on first load.

When to use it

  • Pasting Markdown from a README into a CMS that only accepts HTML
  • Sanity-checking a Markdown draft before committing it to a docs repo
  • Converting meeting notes into HTML to email to non-Markdown colleagues
  • Generating the HTML for a static blog post from a local Markdown file

When not to use it

  • You need to edit Markdown live with a preview — use a real editor like VS Code or Obsidian
  • You need full GFM including mentions, alerts, and the new ::warning:: syntax — this is CommonMark + tables/task lists/strikethrough/fenced code only
  • You need sanitisation for untrusted input — pair this with a sanitiser (DOMPurify) if you intend to render the result in another user's browser

Frequently asked questions

Does it sanitise the HTML?

No. The output preserves raw HTML in the Markdown and script tags will pass through. If you are converting user input for rendering on a public page, run the output through a sanitiser such as DOMPurify before inserting it into the DOM.

Which Markdown dialect is supported?

CommonMark 0.30, plus GitHub-flavoured tables, task lists, strikethrough (~~text~~), and fenced code blocks with a language hint. It does not support footnotes, definition lists, or the newer ::alert:: syntax.
