Markdown → HTML Converter
Convert a Markdown document to HTML with a rendered preview.
Category: Converters
When to use?
Use it to convert a README or release notes to HTML for embedding in a web page, or to see how a Markdown document renders as real HTML.
How to use
- Paste or type Markdown in the input.
- Check the rendered preview on the right.
- Use the copy HTML button to take the converted HTML.
Input Explanation
Write Markdown syntax (e.g. # heading, **bold**) in the left input to convert to HTML tags.
Calculation Basis
It parses text with a Markdown parser like marked.js into an HTML AST, then filters malicious scripts (XSS) with DOMPurify to render safe HTML.
Usage Examples
- Convert docs to HTML - Convert a README or release notes into an HTML fragment.
- Check rendering - See how Markdown actually looks in the browser.
- Write email bodies - Convert Markdown content to HTML for an email template.
Examples
- # Hello → <h1>Hello</h1>
- A doc mixing lists and **bold** → HTML source with ul and strong tags
Cautions
- Malformed source data can cause parsing errors or broken output.
- A mismatched encoding standard or complex nested data may break or drop the structure.

FAQ
Do HTML tags run as-is?
Dangerous HTML is escaped and the rendered result is sanitized.
Are code blocks and lists supported?
Yes — headings, lists, links, blockquotes, code blocks, and other basic Markdown syntax.
How is this different from the Markdown preview tool?
The preview tool shows the rendered result; this tool focuses on taking the converted HTML source.
Can I copy the converted HTML?
Yes. Copy the converted HTML source to paste into a web page or template.
