About this tool
Markdown is the plain-text formatting syntax behind README files, documentation, blog platforms, and chat apps, but it's easy to get small details wrong — a missing blank line before a list, or mismatched table pipe counts — without seeing the rendered result. This tool renders your Markdown live as you type, side by side with the raw source, so you can immediately see how headers, bold and italic text, links, tables, code blocks, and blockquotes will actually appear. It's useful for drafting a GitHub README, checking documentation formatting before publishing, or simply learning Markdown syntax by trial and error. Everything renders locally in your browser using JavaScript, with nothing sent to a server.
Frequently asked questions
What Markdown flavor does it support?
Common GitHub-Flavored Markdown features are supported, including tables, fenced code blocks with syntax highlighting, task lists, and standard headers/emphasis/links.
Does it support syntax highlighting in code blocks?
Yes — fenced code blocks with a language specified (like ```javascript) are highlighted accordingly in the preview.
Can I export the rendered HTML?
Yes, the rendered output can be copied or downloaded as HTML for use elsewhere.
Why isn't my table rendering correctly?
Markdown tables require a header separator row (e.g. |---|---|) directly below the header row, and consistent pipe counts across rows — a common source of rendering issues.
Does the preview update as I type?
Yes, the preview re-renders live with every keystroke so you can see formatting changes immediately.
