What this Markdown to HTML converter does

Markdown is how most of us write — in notes apps, GitHub READMEs, documentation and static-site content — but the web ultimately renders HTML. This converter translates the standard Markdown constructs into clean, semantic HTML tags, live as you type. A toggle switches the output pane between the raw HTML code (to copy into a page, email template or CMS) and a rendered preview (to check the result looks the way you intended).

The conversion is conservative by design: input is HTML-escaped first, so stray angle brackets in your text cannot inject markup into the output.

How to convert Markdown to HTML

  1. Paste or write Markdown in the left pane — a sample document is loaded to start.
  2. Switch the right pane between HTML code and Preview.
  3. Click Copy HTML and paste it wherever HTML is accepted.

Where converted HTML is useful

Typical destinations: CMS body fields that accept HTML but not Markdown, HTML email builders, static pages without a build step, and rich-text widgets in older platforms. Before publishing long content, run the source text through the Word Counter to check length and reading time.

Frequently asked questions

What Markdown syntax does this converter support?

The common core: headings (# through ######), bold and italic, inline code and fenced code blocks, links, unordered and ordered lists, blockquotes, horizontal rules and paragraphs. That covers the Markdown used in READMEs, notes and CMS content.

Is the generated HTML safe to paste into my site?

The converter escapes raw HTML in your input before processing, so pasted angle brackets become text rather than live markup. As with any user-generated content, sanitize on the server too if the Markdown comes from untrusted users.

Why does Markdown exist if HTML already does the job?

Markdown is faster to write and easier to read as plain text: *emphasis* beats <em>emphasis</em> while drafting. HTML remains what browsers render, so converting Markdown to HTML is the bridge between comfortable writing and web publishing.

Can I convert HTML back to Markdown here?

This tool converts one way, Markdown to HTML, which is the direction publishing workflows need. Rendered preview mode lets you verify the result before copying the code.
