Why convert Markdown to HTML
Markdown is the writer's format; HTML is the web's format. Whenever Markdown needs to render in a browser — a CMS, a static site, an email template, a documentation portal — it has to be converted to HTML first.
Static-site generators like Hugo, Jekyll, Eleventy, and Next.js MDX all convert Markdown to HTML under the hood. Our converter does the same thing in one click, useful when you need to inspect the output, paste into a CMS, or hand HTML to a teammate who does not use Markdown.
Developer tooling, blog platforms, and documentation systems often accept Markdown directly — but when they do not, you need the HTML. Examples: WordPress (without a plugin), some Webflow imports, plain email templates, embed snippets.
Our output is semantic and clean. Headings become h1-h6, lists become ul/ol/li, code becomes pre/code, links become anchors. No inline styles, no class soup — bring your own CSS or pipe it into your design system.
Common use cases
- Paste an article from Markdown into a CMS that does not accept Markdown.
- Generate HTML for a static-site post when your generator is misbehaving.
- Convert a README to HTML for documentation that ships outside GitHub.
- Create an email-template snippet from a Markdown source.
- Render Markdown to HTML for sanitization and re-embedding in a web app.
Tips for best results
- We output semantic HTML with no inline styles. Apply your own CSS to control appearance.
- GFM tables, task lists, and fenced code blocks are supported alongside standard CommonMark syntax.
- Fenced code blocks with a language hint (```js, ```python) include the language as a class on the <code> element so syntax-highlighting libraries can pick it up.
- Raw HTML inside Markdown passes through unchanged. Sanitize the output if you re-embed it in a user-facing context.
- Headings include id attributes derived from heading text — useful for anchor links and tables of contents.
About Markdown
Markdown is a lightweight plain-text formatting language created by John Gruber in 2004 and standardized as CommonMark in 2014. It is intentionally minimal: headings with #, lists with - or 1., emphasis with *, links with [text](url). GitHub Flavored Markdown extends it with tables, task lists, fenced code blocks, and strikethrough. Markdown is the dominant format for READMEs, static-site content, documentation, and note-taking — anywhere writers want plain text to render as formatted prose.
About HTML
HTML (HyperText Markup Language) is the language of the web. Every browser, CMS, email client, and documentation tool understands HTML. As a target format, HTML is the natural rendering destination for any text-first source. Semantic HTML — using h1-h6, ul/ol/li, pre/code, blockquote, table — gives both browsers and screen readers a clean structural view of the document, which is what our converter produces.

Frequently asked questions
Which Markdown dialect do you support?+
CommonMark plus GitHub Flavored Markdown extensions: tables, task lists, fenced code blocks, strikethrough.
Will the HTML be styled?+
No. We output semantic HTML without inline styles. Apply your own CSS or pipe the markup into your design system.
Will the output be safe to embed in a user-facing web app?+
Markdown can contain raw HTML, which passes through. If you re-embed user-submitted markup, sanitize with DOMPurify or similar before rendering.
Is the Markdown to HTML converter free?+
Yes. 5 conversions per day as a guest, 10 per day signed in with Google. No card.
Do headings get id attributes?+
Yes — heading text is slugified and added as the id, so anchor links (#my-heading) work out of the box and a TOC generator can build the index automatically.
Is it safe to upload my Markdown?+
Yes. Files are uploaded over HTTPS and deleted from our servers within one hour. We never train models on your content.
Does it work on Mac, Windows, iPhone, and Android?+
Yes. The converter runs in any modern browser. The HTML output is universally compatible.
Can I get HTML with inline CSS instead?+
Not in this conversion path. Inline-styled HTML for email templates is on our roadmap as a separate option.
