Markdown to HTML Converter
Convert Markdown to HTML and HTML back to Markdown — GitHub-flavored, 100% in your browser.
Markdown → HTML supports GitHub-flavored Markdown (headings, lists, code, tables, links).
About Markdown to HTML Converter
Paste Markdown to get HTML, or switch direction to convert HTML back into Markdown. Markdown rendering supports GitHub-flavored Markdown — headings, bold and italic, lists, links, images, blockquotes, fenced code blocks and tables.
The HTML-to-Markdown direction produces clean, readable Markdown with ATX headings and fenced code blocks. Everything runs locally in your browser; nothing you paste is uploaded.
How to use Markdown ⇄ HTML
- Choose Markdown to HTML or HTML to Markdown and paste a short representative document.
- Inspect headings, links and lists in the generated source before publishing it.
Limitations and common mistakes
Markdown dialects support different extensions, and HTML to Markdown can lose presentation details or unsupported structures.
Conversion is not sanitization. Treat HTML derived from untrusted input as untrusted, and sanitize it for the exact publishing context before rendering it on a website.
The tool processes its input locally on your device. Read our privacy policy for analytics, storage and network details.

Frequently asked questions
Does it support GitHub-flavored Markdown?
Yes. Tables, fenced code blocks, task lists and other GFM features are supported when rendering Markdown to HTML.
Can it convert HTML back to Markdown?
Yes. Switch to HTML → Markdown to turn existing HTML into clean Markdown with ATX headings and fenced code blocks.
Is the HTML sanitized?
The tool outputs the HTML as text for you to copy; it doesn't render untrusted HTML, so there's nothing to execute.
Is my content uploaded anywhere?
No. Both conversions happen locally in your browser.
