What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004 that converts simple text formatting syntax into HTML. It is widely used for README files, technical documentation, blog posts, forums, and note-taking apps. Its simplicity makes it easy to learn and read even in raw text form.
Type or paste Markdown in the left editor and see the rendered HTML preview on the right in real-time. You can also toggle to view the raw HTML output for copying into web pages. Load the sample document to explore all supported Markdown syntax elements at a glance.
Markdown is the standard for GitHub documentation, static site generators like Jekyll and Hugo, knowledge bases like Notion and Confluence, and developer blogs. It is also supported in Slack, Discord, Reddit, and many other platforms where formatted text is needed without a rich text editor.
Core Markdown syntax includes headings (#), bold (**text**), italic (*text*), links, images, code blocks with backticks, ordered and unordered lists, blockquotes, and horizontal rules. GitHub Flavored Markdown adds tables, task lists, strikethrough, and syntax-highlighted code fences for popular programming languages.
