Output HTML

Preview

Convert Markdown to a complete HTML file ready to publish on a blog, send via email, paste into WordPress, or import into Notion. Supports GitHub-flavored Markdown (tables, task lists, code blocks).

When to convert Markdown → HTML

Publishing on WordPress: WordPress doesn't understand Markdown — paste HTML into the "Text" tab.
HTML email: write content in Markdown, convert to HTML, paste into Gmail / Outlook.
Newsletters: Mailchimp, Substack sometimes need raw HTML for custom layouts.
Static documentation: produce a single .html file to share with colleagues without installing tools.
Convert ChatGPT/Claude output: AI returns Markdown — convert to HTML and publish immediately.

3 CSS themes

GitHub Markdown CSS: looks like a GitHub README — clean, familiar, light-gray code blocks.
Clean / Minimal: serif font (Georgia) for long-form reading — Medium / Substack style.
No CSS: raw HTML to paste into a CMS that has its own theme (WordPress, Ghost) — avoids style conflicts.

Automatic dark mode

Enable "Dark mode support" → the tool adds @media (prefers-color-scheme: dark). The exported HTML automatically swaps colors based on the reader's OS setting.

Standalone vs body-only

Standalone file (default): includes <html>, <head>, <style> — open it in a browser directly.
Body-only: returns just the inner HTML — paste into WordPress, Notion, or embed in another page. Turn off "Standalone HTML file".

GitHub-flavored Markdown — what's supported

Headings 1-6, paragraphs, bold / italic / strikethrough.
Bullet and numbered lists, multi-level nested.
Tables with column alignment (:---: center, :--- left, ---: right).
Code blocks with language hint (```js, ```python).
Inline code, links, images.
Blockquotes, horizontal rules (---).
Task lists (- [x] done, - [ ] todo).
Auto line breaks (2 trailing spaces or a blank line).

Privacy

Everything runs in your browser. Markdown is NOT uploaded to any server — safe for sensitive content like internal docs or unannounced plans.

FAQ

How does this differ from the Markdown Preview tool?

Markdown Preview only renders for viewing. This tool EXPORTS A COMPLETE HTML FILE with <html>, <head>, <style> ready to download (.html), email, or paste into WordPress. You also get 3 CSS themes and automatic dark mode.

Does it support GitHub-flavored Markdown?

Yes. The tool uses the marked library with GFM enabled — table column alignment, task lists (- [x] done), code blocks with language hints, strikethrough, autolinks. Covers ~95% of what you write on GitHub.

How do I paste into WordPress without style conflicts?

Disable "Standalone HTML file" so you only get the body HTML (no inline CSS), or pick the "No CSS" theme. Then in WordPress switch to the "Text" tab (not "Visual") and paste. The active theme will style it.

Can I send the exported HTML by email?

Yes, but for old Outlook (2016-) you may need to inline the styles. The tool exports HTML with a <style> block — Gmail and modern Outlook handle that fine. For full inline conversion, run the output through a CSS-inliner like https://templates.mailchimp.com/resources/inline-css/ before sending.

Does the tool upload my Markdown anywhere?

No. All conversion runs in your browser via JavaScript. Your Markdown never leaves your machine — safe for internal docs, contracts, and sensitive content.
