Blockquotes

Markdown is a lightweight markup language with plain-text-formatting syntax, created in 2004 by John Gruber with Aaron Swartz.

Markdown is often used to format readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor.

How to use the Markdown Reader

  1. Write or paste Markdown into the editor panel on the left side. The tool supports the full CommonMark specification including GitHub Flavored Markdown (GFM) extensions.
  2. Preview in real-time as you type. The right panel renders your Markdown instantly, showing exactly how your document will look when published.
  3. Use the toolbar for quick formatting. Insert headers, bold, italic, links, images, code blocks, and tables without memorizing the syntax.
  4. Export your work by copying the rendered HTML or the raw Markdown source. Use the HTML output to paste directly into CMS platforms, emails, or web pages.

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write formatted text using a plain-text editor with simple, human-readable syntax. Instead of clicking buttons in a rich text editor, you use characters like # for headings, * for emphasis, and - for lists.

The beauty of Markdown is its portability. A .md file is just plain text, so it works everywhere: Git repositories, documentation platforms like Read the Docs, note-taking apps like Obsidian, and static site generators like Hugo and Jekyll. GitHub, GitLab, and Bitbucket all render Markdown files automatically, which is why README.md has become the universal standard for project documentation.

Key syntax elements include:

  • Headings: # H1, ## H2, ### H3 (up to six levels)
  • Emphasis: *italic*, **bold**, ~~strikethrough~~
  • Lists: - or * for unordered, 1. for ordered
  • Links: [text](url)
  • Images: ![alt](url)
  • Code: backticks for inline code, triple backticks for fenced code blocks with optional language highlighting
  • Tables: pipe-delimited columns with a separator row

GitHub Flavored Markdown adds task lists (- [x]), auto-linked URLs, and syntax-highlighted code fences, making it especially powerful for developer documentation.

Common use cases

  • Writing README files for open source projects on GitHub, GitLab, or Bitbucket so collaborators and users can quickly understand the project.
  • Drafting blog posts for static site generators (Hugo, Jekyll, Gatsby) or headless CMS platforms that accept Markdown input.
  • Creating technical documentation with code samples, tables, and structured headings that render beautifully on documentation hosting platforms.
  • Taking structured notes that remain readable in any text editor and can be synced across Markdown-compatible apps like Obsidian, Notion, or Typora.

FAQ

Q: Does this tool support GitHub Flavored Markdown (GFM)? A: Yes. The renderer supports GFM extensions including task lists, tables, strikethrough, and auto-linked URLs, so your preview will closely match how GitHub renders your files.

Q: Can I use HTML inside my Markdown? A: Most Markdown parsers, including this one, allow inline HTML. You can mix HTML tags with Markdown syntax for advanced layouts, although pure Markdown is preferred for readability and portability.

Q: How do I add syntax-highlighted code blocks? A: Use triple backticks followed by the language name. For example, writing three backticks then javascript before your code and three closing backticks after will produce a highlighted JavaScript block.
