Markdown to HTML

Type or paste your Markdown into the editor on the left and the HTML is generated instantly. Use the Preview tab to see how it will look rendered, or switch to the HTML tab to read and copy the underlying markup. The conversion happens live as you type — there is no "convert" button to press and nothing to upload. When you are happy with it, click "Copy HTML" to grab the markup or "Download" to save it as an .html file.

Yes. The converter uses GitHub Flavored Markdown, so tables, fenced code blocks, strikethrough, task lists (- [ ] and - [x]) and automatic links all work the same way they do in a GitHub README or issue. You can also turn on "single line breaks" in the options if you want every newline to become a line break, the way comments behave on GitHub, instead of the standard Markdown behavior of merging lines into one paragraph.

The HTML is sanitized before it is shown or copied: scripts, inline event handlers (like onclick) and dangerous URLs such as javascript: are stripped out, while normal formatting — headings, lists, links, images, tables and code — is kept. That means you can safely paste Markdown from anywhere, including a README or a document someone sent you, and preview it without the risk of running hidden code.

Absolutely. Paste any Markdown — a README, notes, documentation or a chat message — and the live Preview renders it exactly as it would appear, so it doubles as a Markdown viewer. Because everything runs in your browser it works offline once loaded and updates the moment you edit, which makes it handy for drafting and proofreading Markdown before publishing it.

No. The entire conversion runs locally in your browser with JavaScript, so the Markdown you type or paste and the HTML it produces never leave your device and are never sent to or stored on any server. You can convert private notes, internal documentation or confidential content with confidence, and the tool keeps working even with no connection.
