Markdown to HTML Converter — Free Online Tool
The free Markdown to HTML Converter turns Markdown source into clean, ready-to-use HTML instantly — with a live side-by-side view, one-click copy, and zero external dependencies. Everything runs in your browser; nothing is sent to a server.
Why Convert Markdown to HTML?
Markdown is the standard authoring format for READMEs, documentation, blog drafts, and wiki pages — but most web pages, CMSs, and email clients expect HTML. Converting Markdown to HTML lets you:
- Paste formatted content directly into WordPress, Ghost, or Webflow custom HTML blocks
- Generate HTML snippets for email templates without hand-coding tags
- Preview how your Markdown will render as web content before publishing
- Extract clean semantic markup from documentation written in Markdown
How to Use the Converter
- Open the Markdown to HTML Converter. A sample document is pre-loaded so the conversion is visible immediately.
- Replace the sample with your own Markdown in the left panel. The HTML output updates live in the right panel as you type.
- Review the output. Line and character counts appear below each panel so you can track the size of both the source and the output.
- Click Copy HTML to copy the full output to your clipboard. Paste it directly into your editor, CMS, or code base.

Using the HTML Output in Practice
WordPress and page builders
In WordPress, switch the block editor to a Custom HTML block, paste the converted output, and save. The markup renders with your theme's styles applied to the semantic tags. The same approach works in Elementor, Divi, and Beaver Builder — look for an HTML or code widget.
Ghost CMS
Ghost natively supports Markdown, but if you need to inject raw HTML (for special formatting or embeds), paste the converted output into a HTML card in the Ghost editor. This bypasses Ghost's own Markdown renderer and gives you direct control over the markup.
Email templates
Email clients strip most CSS but respect basic semantic tags. Converting Markdown to HTML gives you <strong>, <em>, <ul>, and <ol> elements that render correctly across Gmail, Outlook, and Apple Mail. Inline the CSS manually or run the output through an email-specific CSS inliner before sending.
Beautifying the output
The converter produces compact, valid HTML with newlines between block elements. If you want human-readable indented markup for code review or documentation, copy the output and paste it into the JS Beautifier — it handles HTML formatting cleanly.
Comparing versions
When you update your Markdown and want to see what changed in the HTML output, paste both versions into the Diff Checker. It highlights added, removed, and unchanged lines so you can catch unintended changes before publishing.
Common Questions
Does the converter need an internet connection to work?
Only to load the page initially. Once loaded, the conversion runs entirely in your browser using a JavaScript parser built into the tool. No network requests are made during conversion — it works offline after first load.
Does the output include a full HTML document structure?
No. The converter outputs HTML fragments — the content between <body>tags, not a full document. This is intentional: you almost always want to embed the output inside an existing page template rather than replace the whole document. Wrap it in your own <html>, <head>, and <body>tags if you need a standalone file.
Is there a file size or character limit?
No enforced limit. The parser processes text synchronously in the browser, so very large documents (hundreds of thousands of characters) may cause a brief UI lag on older devices. In practice, typical Markdown documents convert instantly regardless of length.
