Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write formatted text using plain text syntax that is easy to read and write. Markdown is widely used for documentation, README files, blog posts, comments, and messaging. It is the standard format on GitHub, GitLab, Stack Overflow, Reddit, and many other platforms.
How This Tool Works
This Markdown previewer parses your input in real time using a custom regex-based parser built entirely in the browser. It converts standard Markdown syntax — headings, bold, italic, code blocks, lists, links, images, blockquotes, tables, and horizontal rules — into styled HTML. No external libraries or server requests are involved. The generated HTML can be copied with one click.
Supported Markdown Syntax
This tool supports the most commonly used Markdown elements: headings (h1-h6), bold, italic, strikethrough, inline code, fenced code blocks, ordered and unordered lists, links, images, blockquotes, tables with alignment, and horizontal rules. It covers the syntax you will use in the vast majority of Markdown documents.
Frequently Asked Questions
Is my Markdown saved anywhere?
No. Everything runs locally in your browser. Your Markdown content is not sent to any server or stored anywhere. Refresh the page and it resets to the default sample.
Can I use this for GitHub README files?
Yes. This tool supports standard Markdown syntax that is compatible with GitHub Flavored Markdown (GFM), including tables, fenced code blocks, and strikethrough. It is a great way to preview your README before committing.
Does it use any external Markdown libraries?
No. The Markdown parser is a custom implementation built with regex replacements. It handles common patterns without relying on libraries like marked, remark, or markdown-it.
