Markdown to HTML converter parses CommonMark and GFM Markdown and produces clean, semantic HTML. The three-panel layout shows your source Markdown, the generated HTML, and a live visual preview simultaneously — entirely in your browser, no data sent anywhere, completely free.
The parser supports the full CommonMark specification plus GitHub Flavored Markdown extensions: ATX headings (# H1) and Setext headings; paragraphs, hard line breaks, and soft line breaks; bold (**text**), italic (*text*), strikethrough (~~text~~), inline code; links, images, autolinks; fenced and indented code blocks; ordered and unordered lists including nested; task list checkboxes (- [x]); blockquotes; horizontal rules; and pipe tables.
Fragment mode outputs only the HTML tags that correspond to your Markdown content — the equivalent of the content inside a <body> element. Full document mode wraps the content in a complete HTML page with <!DOCTYPE html>, <html>, <head> with charset and viewport meta tags, and a <body>. Use full document mode when you want a self-contained HTML file you can open in a browser.
A fenced code block with a language specifier like ```javascript is converted to <pre><code class="language-javascript">...</code></pre>. The language-* class follows the convention used by syntax highlighting libraries like Prism.js and highlight.js, so the output is ready to use with any of those libraries.
Task lists are a GFM extension that converts - [ ] item and - [x] item to HTML list items with disabled checkboxes: <input type="checkbox" disabled>. Checked items use <input type="checkbox" disabled checked>. This is the format used in GitHub issues, pull requests, and README files for tracking to-do items.
GFM pipe tables are converted to HTML <table> elements with <thead>, <tbody>, and <th>/<td> cells. Column alignment is set using text-align inline styles based on the colon position in the separator row (:--- for left, ---: for right, :---: for center). Tables with no alignment colons default to left-aligned.
Yes. The HTML output uses standard semantic elements — <h1>–<h6>, <p>, <ul>, <ol>, <table>, <blockquote>, <pre>, <code> — with no inline styles or framework-specific classes. The output is compatible with any CSS framework including Bootstrap, Tailwind, and Bulma's typography/prose utilities.
Markdown is the most widely used lightweight markup language for writing formatted content in plain text. It is the native format for GitHub READMEs, documentation sites built with Jekyll and Hugo, note-taking apps like Obsidian and Notion, and countless developer tools. When that content needs to be embedded in a web page, email template, or CMS, it must be converted to HTML. This tool performs that conversion instantly with a live preview.
CommonMark is the most rigorously specified version of Markdown, resolving the ambiguities that existed in John Gruber's original specification. GitHub Flavored Markdown (GFM) extends CommonMark with tables, task list checkboxes, strikethrough, and autolinks. This converter implements both, producing HTML that matches what GitHub renders for README files and Markdown documents.
Fenced code blocks with language identifiers are converted to <pre><code class="language-identifier"> elements. This class naming convention is used by Prism.js, highlight.js, and all major browser-side syntax highlighting libraries. If you paste the output into a page that includes one of those libraries, the code blocks will be automatically highlighted in the correct language.
The fragment mode produces clean HTML that can be inserted inside any existing page body — no <!DOCTYPE>, no <html>, just the content tags. This is the right output for embedding in a CMS, a static site template, or a JavaScript application. The full document mode wraps the output in a complete HTML5 document with a charset meta tag and viewport declaration, producing a file you can save and open directly in a browser.
GFM tables support column alignment through colon syntax in the separator row. | :--- | produces left-aligned cells, | ---: | produces right-aligned cells, and | :---: | produces centred cells. The converter preserves these alignments in the HTML output using text-align inline styles on the <th> and <td> elements, which ensures alignment is preserved even when the output is used without any external stylesheet.
