Markdown to HTML Converter

What is Markdown?

Markdown is a plain-text formatting syntax that converts to HTML. Designed to be readable as-is, it uses intuitive conventions like **bold**, *italic*, and # Heading that mirror how people naturally emphasize text in emails and plain-text documents.

Markdown is the default writing format on GitHub, GitLab, Stack Overflow, Reddit, Discord, and countless documentation tools. Converting it to HTML is the final step before rendering in a browser or embedding in a web page.

Supported Syntax

• Headings — # H1 through ###### H6
• Emphasis — **bold**, *italic*, ~~strikethrough~~
• Lists — ordered (1.), unordered (- or *), and task lists (- [ ])
• Code — inline `code` and fenced blocks with syntax language hints
• Tables — GFM pipe tables with alignment
• Links & images — [text](url) and ![alt](url)
• Blockquotes — > quoted text
• Horizontal rules — ---

Frequently Asked Questions

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain-text syntax (like # for headings, **bold**, and - for lists) that is easy to read and write, and converts to clean HTML. It is widely used for README files, documentation, blog posts, and note-taking apps.

What is GitHub Flavored Markdown (GFM)?

GitHub Flavored Markdown (GFM) is a superset of standard Markdown used on GitHub and many other platforms. It adds support for tables, fenced code blocks (```), strikethrough (~~text~~), task lists (- [ ]), and autolinks. This tool uses GFM by default.

What Markdown features are supported?

This tool supports headings (# to ######), bold (**text**), italic (*text*), blockquotes (>), ordered and unordered lists, inline code (`code`), fenced code blocks (```), horizontal rules (---), links ([text](url)), images (), tables, strikethrough (~~text~~), and task lists.

How do I use the rendered preview?

Click the "Show Preview" button below the textareas. A live preview panel will appear showing the Markdown rendered as formatted HTML. The preview updates in real time as you type. Click "Hide Preview" to dismiss it.

Is my content safe?

Yes. This tool runs entirely in your browser — no data is ever sent to a server. The rendered preview displays the HTML output directly in the page. Be cautious when copying output HTML that contains user-supplied content into your own pages, as Markdown can include raw HTML.
