How to use the Markdown to HTML converter
- Paste or type Markdown in the left box.
- The HTML code appears on the right instantly, with a rendered preview below.
- Click Copy HTML and paste it into your website, CMS, email template or blog.
Supported Markdown syntax
The converter handles the everyday Markdown you actually use: headings (# … ######), bold and italic, inline code and fenced code blocks, links and images, ordered and unordered lists, blockquotes, and horizontal rules. Blank lines separate paragraphs, exactly as standard Markdown expects.
Benefits
- Instant conversion with both the HTML source and a rendered preview, so you can sanity-check the result.
- Handles the Markdown you actually use daily: headings, emphasis, links, images, lists, quotes and code blocks.
- One-click copy of the generated HTML.
- Runs locally in your browser — paste sensitive drafts without them leaving your device.
Limitations to know
- It covers core Markdown; GitHub-flavored extras like tables, task lists and footnotes are not converted.
- It converts one way only — there is no HTML-to-Markdown mode.
- Code blocks are converted to plain <pre><code> without syntax highlighting.
Common mistakes to avoid
- Forgetting the blank line between paragraphs — Markdown joins consecutive lines into one paragraph.
- Starting list items mid-line or without a space after the dash, so they render as plain text.
- Pasting the rendered preview into your CMS instead of the HTML code.
Alternatives
To tidy JSON instead of Markdown, use the JSON Formatter; to check the length of your draft first, try the Word Counter.

Frequently asked questions
Is my text sent to a server?
No — the conversion happens entirely in your browser. Nothing is uploaded or stored.
Which Markdown flavor is this?
Standard core Markdown — the common syntax shared by CommonMark and GitHub-Flavored Markdown. Advanced GFM extras like tables and task lists aren't converted.
Can I convert HTML back to Markdown?
Not in this tool — it converts one way, Markdown → HTML.
Why does my list not render?
Make sure each list item starts at the beginning of its own line with -, * or 1. followed by a space.
