Markdown to HTML Converter

Q: Why are my single line breaks ignored?

In standard Markdown a single newline is a space. Enable **Line break = ** to keep them, like GitHub comments do.

When to use Markdown to HTML

Use it to turn README text, blog drafts or documentation into HTML for a CMS or email. The raw HTML output is not sanitized – if the Markdown comes from untrusted users, sanitize the HTML on your server before publishing it.

How Markdown to HTML works

Markdown is converted with marked, a CommonMark-compatible parser, with GFM extensions when enabled. The raw HTML output is exactly what marked generates, including any HTML you wrote inside the Markdown. The preview is passed through DOMPurify first, which removes scripts, event handlers such as onerror and other dangerous markup before it is displayed.

Common Use Cases

Convert a README section into HTML for a website
Prepare HTML for a CMS that has no Markdown support
Check how GitHub-style tables render
Write HTML email content in Markdown

FAQs

Is the output HTML safe?

The preview is sanitized with DOMPurify. The raw HTML is returned unchanged so you can see what marked produced; sanitize it yourself before publishing untrusted content.
