Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write using an easy-to-read, easy-to-write plain text format that converts to structurally valid HTML. Markdown is now the standard format for README files, documentation, blog posts, and technical writing.
This Markdown to HTML converter renders your Markdown in real-time using the marked.js library, which implements the CommonMark specification and GitHub Flavored Markdown (GFM) extensions. You can see the rendered preview on the right panel, or toggle to view the generated HTML code.

Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language designed by John Gruber and Aaron Swartz in 2004. It uses plain text with simple punctuation-based formatting that converts to HTML. The name is a play on "markup language" — it's a "down" version that's easier to write and read than raw HTML.
What is the difference between Markdown and HTML?
HTML (HyperText Markup Language) uses verbose tag syntax like <strong>bold</strong>, <h1>Heading</h1>, etc. Markdown uses simpler shortcuts: **bold** and # Heading. Markdown is easier to write and read, but must be converted to HTML for display in browsers.
What is GitHub Flavored Markdown (GFM)?
GitHub Flavored Markdown is a superset of CommonMark that adds extensions like tables (| col | col |), task lists (- [x] item), strikethrough (~~text~~), and automatic URL linking. GFM is the standard used in GitHub README files, issues, pull requests, and wikis.
Can I use this to convert README.md files?
Yes! Paste the contents of any README.md or other Markdown file into the editor. The converter supports the same GFM syntax used by GitHub, so your README will render identically to how it appears on GitHub.
Does this tool convert Markdown to PDF?
This tool converts Markdown to HTML. To create a PDF, you can convert the Markdown to HTML using this tool, then print the preview page to PDF using your browser's print function (Ctrl+P → Save as PDF). Or use the "Download" button to save the HTML file and open it in a browser to print.
Is there a file size limit?
No — this converter processes everything 100% in your browser using JavaScript. There are no server uploads or file size limits. Very large documents (1MB+) may cause slight delays in the live preview but will still convert correctly.
