Markdown to HTML Converter — Convert Markdown Online Free [2026]

Convert Markdown to HTML instantly online. Paste your Markdown and get clean, formatted HTML with support for headers, lists, code blocks, links, and more.

What is Markdown to HTML Converter?

Markdown is a lightweight markup language created by John Gruber in 2004. It allows writers to format text using simple symbols — for example, # for headings, **text** for bold, and [text](url) for links — without writing raw HTML. Markdown is widely used in documentation (README files, wikis), blogging platforms, note-taking apps, and developer tools because it is fast to write and easy to read in its raw form. However, to display Markdown properly on a web page, it must be converted to HTML. This tool performs that conversion instantly in your browser. Paste any Markdown — from simple paragraphs to complex documents with code blocks, lists, and tables — and get valid, clean HTML ready to paste into any web page or CMS.

How to Use Markdown to HTML Converter

Paste your Markdown text into the left input panel. Click "Convert to HTML" to transform it into clean HTML output. The result appears in the right panel — use "Copy HTML" to copy the generated HTML code to your clipboard. Click "Clear" to reset both panels and start fresh.

How Markdown to HTML Converter Works

The converter applies a series of regex-based transformations to your Markdown text: 1. **Code blocks** (``` fenced blocks) are extracted first and preserved to prevent inner content from being processed. 2. **Headings** (# H1 through ###### H6) are converted to <h1>–<h6> tags. 3. **Bold** (**text**) becomes <strong>, **italic** (*text*) becomes <em>. 4. **Unordered lists** (lines starting with - ) are grouped into <ul><li> structures. 5. **Ordered lists** (lines starting with 1. ) are grouped into <ol><li> structures. 6. **Blockquotes** (> text) become <blockquote> elements. 7. **Horizontal rules** (---) become <hr /> tags. 8. **Links** ([text](url)) become <a href="url"> tags. 9. **Inline code** (`code`) becomes <code> tags. 10. **Paragraphs** are formed from blocks of text separated by blank lines, wrapped in <p> tags. All processing happens entirely in your browser — no text is sent to any server.

Frequently Asked Questions

What Markdown syntax does this converter support?▼

This converter supports the most common Markdown elements: headings (# to ######), bold (**text**), italic (*text*), unordered lists (- item), ordered lists (1. item), code blocks (``` fenced), inline code (`code`), links ([text](url)), blockquotes (> text), and horizontal rules (---). Paragraphs are created from text separated by blank lines.

Does this tool support GitHub Flavored Markdown (GFM)?▼

This tool supports the core Markdown specification used in GFM. It handles the most common elements including fenced code blocks and links. Some GFM-specific extensions like tables and task list checkboxes are not fully supported. For full GFM support, a library like marked.js or remark is recommended.

Is the generated HTML safe to use on a website?▼

The HTML generated by this tool reflects the structure of your Markdown input. If your Markdown contains raw HTML or JavaScript, those will pass through to the output. Always sanitize HTML before rendering user-supplied content to prevent XSS attacks. For trusted content (your own writing), the output is safe to use directly.

What is the difference between Markdown and HTML?▼

Markdown is a simplified writing syntax designed to be readable in its raw form. HTML is the markup language that web browsers render. Markdown is easier and faster to write — for example, **bold** is easier than <strong>bold</strong> — but browsers only understand HTML. Converting Markdown to HTML is the step that makes it displayable on the web.

Can I convert HTML back to Markdown?▼

HTML-to-Markdown conversion is the reverse process and requires a different tool. While it is technically possible for simple HTML, complex HTML with nested elements and inline styles is difficult to convert back to clean Markdown. Check our HTML to JSX converter for related transformations.
