Markdown is a lightweight markup language that lets you format plain text using simple syntax — headings with #, bold with **text**, links with [label](url), and more. It is widely used in README files, documentation, blog posts, and note-taking apps like GitHub, Notion, and Obsidian.
This free online Markdown editor gives you a split-pane workspace: write raw Markdown on the left with VS Code–style syntax highlighting, and see a live GitHub-style rendered preview on the right as you type. You can copy the raw Markdown to your clipboard, download it as a .md file, or export the rendered preview as a self-contained HTML file — all without creating an account.
Supported syntax includes headings, emphasis, lists, task lists, blockquotes, inline and fenced code blocks with language labels, tables, links, images, inline HTML, collapsible details sections, footnotes, and horizontal rules — everything you need to write a complete README or documentation page.
