What is Markdown to HTML Conversion?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple plain-text formatting symbols — like # for headings, ** for bold, and - for lists — to add structure to text that can then be converted to HTML. Markdown is designed to be readable in its raw form while also being processable into rich HTML for web display.
GitHub, Reddit, Stack Overflow, Notion, Slack, and virtually every developer tool supports Markdown for documentation, comments, and content authoring. Technical writers use it to write documentation that compiles to HTML; bloggers write in Markdown and publish to HTML; developers use it in README files. Our tool converts Markdown to HTML in real time with a live preview, and lets you copy the generated HTML or download it as a complete HTML file.

Frequently Asked Questions
This tool uses the Marked.js library which supports the full CommonMark specification plus GitHub Flavored Markdown (GFM) extensions. Supported features include: headings (# to ######), bold (**text**), italic (*text*), lists (- or 1.), links ([text](url)), images (), code blocks (```language), inline code (`code`), blockquotes (>), horizontal rules (---), and tables.
Markdown is much faster to write and easier to read. Compare: writing **bold text** in Markdown vs <strong>bold text</strong> in HTML. For technical documentation, blog posts, and README files, Markdown dramatically reduces authoring time and cognitive load. You write content; the converter handles the HTML structure.
Yes. The generated HTML uses standard semantic elements (h1-h6, p, ul, ol, strong, em, code, pre, blockquote) that work in any browser and integrate into any CMS or framework. You can paste the HTML into WordPress, Webflow, or any HTML editor. The downloaded file is a complete standalone HTML document.
Marked.js generates the correct <pre><code class="language-js"> HTML structure for fenced code blocks. To apply actual syntax colouring, include a syntax highlighting library like Prism.js or Highlight.js in the page that uses the generated HTML — they automatically style the code elements by language class.
