Cómo usar: Markdown Editor

  1. Start typing in the Markdown pane, or open a .md file. The preview updates as you type.
  2. Use the toolbar or shortcuts (Ctrl+B, Ctrl+I, Ctrl+K) to format the selection.
  3. Switch between Split, Editor and Preview layouts, or go full screen for distraction-free writing.
  4. Export with .md, .html or PDF (opens the print dialog — choose “Save as PDF”).

A Markdown editor that runs in your browser

This editor gives you a plain-text writing pane next to a rendered preview, so you can write README files, documentation, blog posts, notes and GitHub issues without installing anything. It understands GitHub-flavored Markdown — tables, task lists, strikethrough and fenced code — and keeps your draft in this browser’s local storage so a refresh doesn’t lose your work.

Markdown cheat sheet

  • # Heading to ###### Heading — six heading levels.
  • **bold**, _italic_, ~~strike~~, `code`.
  • [text](https://example.com) for links, ![alt](image.png) for images.
  • - item or 1. item for lists, - [ ] todo for task lists.
  • > quote, --- for a rule, three backticks for a code block.

Exporting to PDF

The PDF button opens a clean print view of the rendered document. In the print dialog choose Save as PDF as the destination. Headings, tables and code blocks keep their styling, and page margins come from your browser’s print settings.

Preguntas frecuentes

Where is my document saved?
In your own browser’s local storage, every few seconds while you type. Nothing is uploaded. Clearing site data or using a private window removes it, so download a .md copy of anything important.
Does it support GitHub-flavored Markdown?
Yes — tables, task lists, strikethrough, autolinks and fenced code blocks, matching what GitHub renders in README files and issues.
How do I save as PDF?
Click PDF. A print view of the rendered document opens; pick “Save as PDF” as the printer.
Is HTML inside Markdown allowed?
Yes. Safe inline HTML such as <details>, <kbd> or <sup> renders; scripts and event handlers are stripped from the preview and exports with DOMPurify.
¿Puedo instalar Markdown Editor como aplicación web y utilizarla sin conexión?
Sí. Markdown Editor es una aplicación web instalable (PWA): se instala desde el navegador, no se descarga desde una tienda de aplicaciones. Haz clic en «Instalar aplicación» en la parte superior de esta página en Chrome o Edge (Windows, macOS, Linux, ChromeOS) o, en Android, utiliza «Compartir» → «Añadir a la pantalla de inicio» en iPhone y iPad, o «Archivo» → «Añadir al Dock» en Safari 17+ en un Mac. A continuación, se abrirá en su propia ventana con su propio icono y, como se ejecuta íntegramente en tu navegador, seguirá funcionando sin conexión. Firefox en el ordenador de sobremesa no permite instalar aplicaciones web. Cómo funciona la instalación.
