What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that converts to HTML. Its simplicity has made it the standard format for README files on GitHub, technical documentation (Docusaurus, MkDocs, GitBook), blog posts (Hugo, Jekyll, Ghost), and note-taking apps (Notion, Obsidian, Bear).
GitHub Flavored Markdown (GFM) extends standard Markdown with tables, task lists, strikethrough text, and emoji support — widely used across developer tools.

Markdown: The Universal Documentation Language
Markdown has become the default writing format for developers, technical writers, and content creators. Every GitHub README, every documentation site (Docusaurus, VitePress, MkDocs), every Notion page, and most developer blogs use Markdown. Its genius lies in simplicity — plain text with minimal formatting syntax that renders beautifully as HTML. Our Markdown viewer supports GitHub Flavored Markdown (GFM) including tables, task lists, strikethrough, autolinks, and fenced code blocks with syntax highlighting across dozens of programming languages.
Writing Better Documentation
Good documentation follows consistent patterns: a clear heading hierarchy, code examples with syntax highlighting, tables for reference data, and task lists for setup instructions. Markdown enforces these patterns naturally through its syntax. Our viewer renders your Markdown in real time, letting you iterate on formatting without committing and pushing to see the result. This is especially useful for README files, CONTRIBUTING guides, API documentation, and architectural decision records (ADRs) where formatting precision matters for readability.
From Markdown to Production
Markdown is the starting point for many production workflows. Static site generators convert Markdown to HTML pages. Documentation platforms render it with custom themes and search. Our Markdown to PDF converter produces professional documents for reports, proposals, and handouts. Preview HTML output with the HTML Viewer. Transform text with the Text Transformer.
