Como 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.

Perguntas frequentes

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.
Posso instalar o Markdown Editor como um aplicativo da web e usá-lo offline?
Sim. O Markdown Editor é um aplicativo da web instalável (PWA) — instalado a partir do seu navegador, não baixado de uma loja de aplicativos. Clique em “Instalar aplicativo” na parte superior desta página no Chrome ou no Edge (Windows, macOS, Linux, ChromeOS) ou, no Android, use “Compartilhar” → “Adicionar à tela inicial” no iPhone e no iPad, ou “Arquivo” → “Adicionar ao Dock” no Safari 17+ em um Mac. Em seguida, ela se abre em uma janela própria com seu próprio ícone e, como é executada inteiramente no seu navegador, continua funcionando offline. O Firefox no desktop não permite a instalação de aplicativos da web. Como funciona a instalação.
