Markdown to HTML: Build Blog Engines and Render Rich Content

Markdown is how developers write. HTML is how browsers render. Converting between them is the foundation of every developer blog, documentation site, and README renderer. Understanding this conversion helps you build better content pipelines.

What Is Markdown to HTML?

Markdown to HTML conversion parses Markdown syntax into semantic HTML elements — headings become h1-h6, emphasis becomes em/strong, and code fences become pre/code blocks. Our Markdown to HTML converter supports GitHub Flavored Markdown (GFM) with tables, task lists, and strikethrough.

How to Use Markdown to HTML on DevToolHub

1. Open the Markdown to HTML tool on DevToolHub — no signup required.
2. Paste or enter your input data in the left panel.
3. See the result instantly in the output panel.
4. Copy the result or download it as a file.

GFM to HTML Conversion

GitHub Flavored Markdown with extended syntax:

# Markdown input
## Task List
- [x] Set up project
- [ ] Write tests
- [ ] Deploy

| Feature | Status |
|---------|--------|
| Auth    | Done   |
| API     | WIP    |

~~deprecated~~ → **new API**

# HTML output
<h2>Task List</h2>
<ul>
  <li><input type="checkbox" checked> Set up project</li>
  <li><input type="checkbox"> Write tests</li>
  <li><input type="checkbox"> Deploy</li>
</ul>
<table>...</table>
<p><del>deprecated</del> → <strong>new API</strong></p>

• Use GFM (GitHub Flavored Markdown) for tables, task lists, and autolinks
• Add syntax highlighting with fenced code blocks: ```javascript
• Sanitize the HTML output if rendering user-submitted Markdown — prevent XSS
