Converted on your device — nothing is uploaded.

How it works

  1. Paste or type your Markdown in the input box — the HTML code output updates live as you type.
  2. Switch between the HTML code view and the rendered preview to check that everything converted correctly.
  3. Click Copy HTML to grab the markup, or enable document wrapping and download a ready-to-open .html file.

Frequently asked questions

Which Markdown syntax does this converter support?
It covers the elements used in almost every document: headings, bold, italic, strikethrough, links, images, inline code, fenced code blocks with language labels, nested ordered and unordered lists, blockquotes, horizontal rules, and GitHub-style tables with column alignment. Extensions like footnotes or task lists are left as plain text rather than converted incorrectly.
Is the generated HTML clean enough to paste into a website or CMS?
Yes. The output uses plain semantic tags — h1 through h6, p, ul, ol, table, blockquote, pre and code — with no framework classes and no inline styles except text-align on aligned table columns. That makes it safe to paste into any CMS, blog engine, or email template where your own stylesheet controls the look.
Is my Markdown uploaded anywhere when I convert it?
No. The conversion runs entirely in your browser with JavaScript; nothing is sent to a server and nothing is stored after you close the tab. You can even load the page, disconnect from the internet, and keep converting.
What does the “wrap in a full HTML document” option do?
By default the tool outputs only the body markup, which is what you want when pasting into an existing page. Enabling the wrap option adds a doctype, html, head and body skeleton with a charset and viewport meta tag, plus a title taken from your first heading — so the downloaded .html file opens as a complete standalone page.
How is this different from a Markdown preview tool?
A preview tool only shows you what the Markdown looks like rendered. This converter produces the actual HTML source code as text you can copy, edit, and reuse — and includes a preview toggle so you can verify the rendered result before you take the code.

About this tool

This tool converts Markdown into clean, portable HTML code. Paste any Markdown document — a README, blog draft, documentation page, or notes exported from an editor — and the equivalent HTML appears instantly in the output pane. Unlike a preview tool, the point here is the code itself: you get readable, properly nested markup that you can copy into a CMS, static site, email template, or any project that expects HTML.

The conversion happens entirely in your browser. A small parser walks your Markdown line by line, recognizing headings, paragraphs, nested lists, blockquotes, fenced code blocks, horizontal rules, and GitHub-style tables, then applies inline rules for bold, italic, strikethrough, links, images, and inline code. All text is HTML-escaped before markup is generated, so characters like angle brackets inside code blocks come through intact. Because no data ever leaves your device, it is safe to convert private notes, internal documentation, or unpublished drafts.

The output is deliberately minimal: semantic tags with no classes and no styling, apart from text-align styles on table columns you aligned with colons in the separator row. Fenced code blocks keep their language as a language-* class, which syntax highlighters such as Prism or highlight.js pick up automatically. If you need a file that opens on its own, tick the wrap option and the download becomes a complete HTML5 document with a proper head section.

A practical tip: use the preview toggle as a final check before copying. Rendered output makes it easy to spot a list that did not nest because of inconsistent indentation, or a table missing its separator row. Two spaces of indentation are enough to nest a list item, and every table needs a line of dashes between the header and the body rows.
