Markdown to HTML Converter
Convert Markdown syntax to clean, semantic HTML with live preview
What is Markdown to HTML Converter?
Markdown is the most popular lightweight markup language for writing structured content without the verbosity of raw HTML. Developers write README files in Markdown, bloggers use Markdown in Ghost and Jekyll, documentation teams use it in GitBook and Notion, and technical writers use it everywhere from GitHub issues to Slack messages. But many platforms — legacy CMSs, email templates, custom HTML pages, and database-driven systems — require actual HTML rather than Markdown syntax. Our free Markdown to HTML Converter handles the translation instantly. Write or paste any Markdown — headings, bold and italic text, links, images, bulleted and numbered lists, code blocks with syntax highlighting, blockquotes, and tables — and see the rendered HTML output side by side. The converter supports the full CommonMark specification as well as GitHub Flavoured Markdown (GFM) extensions including task lists, strikethrough, and tables. The generated HTML is clean and semantic, using proper heading hierarchy (h1–h6), strong and em for emphasis, pre and code for code blocks, and ul/ol/li for lists.
How to Use Markdown to HTML Converter
- 1
Write or Paste Your Markdown
Enter your Markdown content in the input panel. Supports all standard Markdown elements — headings (#), bold (**), italic (*), links ([text](url)), images, lists, code blocks (```), and tables.
- 2
See the HTML Output
The equivalent HTML is generated in real time in the output panel as you type. You can also toggle to a rendered preview to see exactly how the HTML will look in a browser.
- 3
Copy the HTML
Click copy to send the generated HTML to your clipboard. Paste it directly into your CMS, email template builder, HTML page, or database field.
Use Cases
Publishing Markdown Content to HTML-Only CMSs
Legacy CMS platforms like older WordPress installations, custom PHP backends, and email marketing tools accept HTML but not Markdown. Write your content in Markdown for readability and version control, then convert to HTML here before pasting into the CMS editor — preserving all formatting without manually writing HTML tags.
Converting README Files for Documentation Sites
GitHub README files are Markdown but documentation platforms like Confluence, Notion exports, or custom documentation sites sometimes require HTML input. Convert your README here and paste the HTML output into your documentation tool, retaining all headings, code examples, and formatted lists.
Building Transactional Email Templates
Transactional emails with formatted content — onboarding guides, product update announcements, or support articles — are easier to write in Markdown but must be delivered as HTML. Write the email body in Markdown, convert to HTML here, then paste the output into your email template, adding inline styles for email client compatibility.
Features
Full CommonMark and GFM Support
Handles all standard Markdown elements plus GitHub Flavoured Markdown extensions: tables, strikethrough (~~text~~), task lists (- [x]), and fenced code blocks with language tags.
Live Side-by-Side Preview
See the rendered HTML output update in real time as you write Markdown — both the raw HTML code and a visual browser rendering.
Clean Semantic HTML Output
Generates proper, semantic HTML using heading hierarchy (h1–h6), strong/em for emphasis, pre/code for code blocks — not presentational markup.
Syntax Highlighted Code Blocks
Fenced code blocks with a language identifier (```javascript) are converted to HTML with the appropriate language class for CSS-based syntax highlighting.
Frequently Asked Questions
Markdown is a plain-text formatting syntax created by John Gruber in 2004 that converts to HTML. It uses simple symbols to denote formatting: # for headings, ** for bold, * for italic, - for list items. It is the default writing format for GitHub, GitLab, npm, Stack Overflow, Reddit, Notion, Obsidian, Jekyll, Hugo, and most modern documentation tools. It is popular because it is readable as plain text and converts cleanly to structured HTML.
CommonMark is a strict, standardised specification of Markdown syntax that resolves ambiguities in the original informal Markdown definition. GitHub Flavoured Markdown (GFM) is a superset of CommonMark that adds extensions: tables (using | separators), strikethrough (~~text~~), task lists (- [ ] and - [x]), and autolinked URLs. This tool supports both specifications.
Use pipe characters to define columns and hyphens to separate the header row: | Name | Role | |------|------| | Alice | Admin |. Cells are separated by | and the header row is followed by a row of --- (with optional : for column alignment). Tables are a GFM extension and are not part of basic CommonMark.
The Markdown converter wraps code blocks in <pre><code class="language-javascript"> HTML (with the language class from your fenced code block tag). Syntax highlighting requires a separate CSS library — commonly Prism.js or Highlight.js — to be loaded on the page where the HTML is rendered. The converter provides the correct class hooks; the styling library does the visual work.
This tool converts one direction — Markdown to HTML. Converting HTML back to Markdown (reverse-Markdown) is more complex because HTML can express many formatting structures that have no Markdown equivalent. Dedicated tools like Turndown (a JavaScript library) handle HTML-to-Markdown conversion. For the reverse direction, consider using an online HTML-to-Markdown converter.
