Free Markdown to HTML Converter — Live Online Markdown Editor

Compile Markdown to Clean Semantic HTML with Live Preview. Real-time Markdown editor with live rendered preview, clean HTML code generator, and HTML file download.

What is Markdown to HTML and what does it do?

The Markdown to HTML Converter is a real-time publishing utility that translates CommonMark and GitHub Flavored Markdown (GFM) into clean, semantic, and production-ready HTML markup.

Featuring a dual-pane responsive editor with synchronized scrolling, instant syntax highlighting, and an embedded live visual preview, it provides technical writers and developers with an effortless conversion workflow in their browser.

  • Full GitHub Flavored Markdown (GFM) support: tables, strikethrough, task lists, blockquotes, and fenced code blocks.
  • Split-screen responsive layout with side-by-side editing, raw HTML source view, and rendered visual preview.
  • Configurable export options: copy minified HTML, formatted indented HTML, or export directly to a .html file.
  • Real-time word count, character count, and paragraph statistics updated on every keystroke.
  • Client-side processing using marked for instant speed without sending private notes or documentation to remote servers.

How does Markdown to HTML work?

Input text is tokenized and parsed by the marked compiler into an Abstract Syntax Tree (AST), which evaluates inline formatting, block elements, and custom GFM extensions.

The resulting HTML is rendered safely into an isolated DOM sandbox for visual preview and syntax-highlighted in the output code view for immediate clipboard copying or file download.

100% private: all processing happens locally in your browser using client-side WebAssembly, HTML5 Canvas, and modern Web APIs. Your files are never uploaded to any server.
