What is Markdown
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple plain text formatting that converts cleanly to HTML. The goal was to make writing for the web as easy as writing a plain text email — using intuitive characters like asterisks for bold and hashes for headings that look natural even before conversion. Today Markdown is the standard format for GitHub README files, documentation systems, blog platforms, and developer tools.
Supported Markdown syntax
This converter supports all standard CommonMark Markdown plus GitHub Flavored Markdown extensions. Headings use one to six hash symbols. Bold uses double asterisks or underscores. Italic uses single asterisks or underscores. Strikethrough uses double tildes. Inline code uses backticks. Fenced code blocks use triple backticks with an optional language identifier. Unordered lists use hyphens, asterisks or plus signs. Ordered lists use numbers followed by periods. Blockquotes use the greater-than symbol. Tables use pipe characters.
