What is Markdown?
Markdown is a lightweight markup language that lets you write formatted text — headings, bold, links, lists, code blocks — using plain, readable syntax, which is then converted into HTML for display. It's the standard formatting syntax for README files, GitHub comments, and many documentation and blogging tools.
When would I use this?
- Previewing a README.md before pushing it to a repository.
- Drafting a blog post or documentation page and checking how it will render.
- Learning Markdown syntax by experimenting and seeing the output immediately.
How it works
Your Markdown is parsed and converted to HTML entirely with JavaScript in your browser — nothing is sent to a server, and no external rendering service is used.
Frequently asked questions
Headings, bold/italic text, links, images, ordered and unordered lists, blockquotes, inline code and fenced code blocks, horizontal rules, and tables (GitHub-flavored Markdown table syntax).
No, parsing and rendering happen entirely in your browser with JavaScript. Nothing you type is sent to a server.
Yes, paste the contents of any README.md or other Markdown file to see exactly how it will render, close to how GitHub or most Markdown renderers display it.
Raw HTML tags typed directly in the Markdown are escaped rather than executed, to keep the preview safe from accidental script injection.
