Free online Markdown to HTML Converter tool to convert Markdown syntax to HTML code. Transform MD files to HTML markup instantly. All conversion happens locally.

What is Markdown to HTML Converter?

Markdown to HTML converts CommonMark-flavoured Markdown into clean HTML you can paste into a website, email template, or CMS. Supports headings, lists, links, images, code blocks, tables, and inline formatting. Conversion happens in the browser, and the output uses semantic HTML5 tags suitable for accessibility and SEO.

Why use this tool?

  • Works offline after the first page load
  • Lightweight page weight that loads quickly even on slow connections
  • Works on desktop, tablet, and mobile in any modern browser
  • Handles UTF-8 BOM, mixed delimiters, and other edge cases that break simpler converters
  • Round-trips cleanly — convert there and back without losing precision or fidelity

How to use

  1. Paste your source data into Markdown to HTML Converter, or upload a file
  2. Confirm the parsed preview looks correct
  3. Click Convert to produce the output in the new format
  4. Copy the result or download as a file ready for the consuming system

Examples

Convert a README for a blog post

Paste your repo README.md and get HTML ready to drop into Ghost, WordPress, or any CMS that accepts HTML.

Generate email HTML

Write the email body in Markdown for readability, convert to HTML, and paste into your email client's HTML view — much faster than hand-writing tables.

Build static-site content

Useful for SSG users who occasionally need to inline HTML (in a component, in a JSX expression) but prefer authoring in Markdown.

Common use cases

  • Converting documentation to publishable HTML
  • Authoring marketing emails in Markdown and rendering to HTML
  • Generating help-centre articles from Markdown source
  • Preparing release notes for a website or in-app changelog
  • Producing static HTML pages without a full build pipeline

Troubleshooting

Inline HTML got escaped.
CommonMark allows raw HTML by default. If yours is escaped, check the "allow inline HTML" option or switch the dialect to GitHub-flavoured Markdown.
Tables not rendering.
Plain CommonMark doesn't include tables. Enable GFM (GitHub Flavored Markdown) for table, strikethrough, and task-list support.
Code blocks lost their language hint.
Use triple-backtick fences with a language tag (```js). The output adds a language-js class on the <code> tag for syntax highlighters like Prism or highlight.js.
