Markdown to HTML
Write or paste Markdown and get both a rendered preview and the raw HTML source, ready to paste into a CMS, an email template or a README. The converter handles headings, emphasis, lists, links, code, blockquotes and horizontal rules.

What this tool does
A README written in Markdown needs to become HTML for an email template, and a draft for a content management system needs to be checked before it is pasted into a rich-text editor. Markdown is quick to write but a target system often wants markup. This converter handles headings, emphasis, lists, links, code, blockquotes and horizontal rules, showing a rendered preview and the raw HTML side by side as you type. That combination matters: the preview tells you whether the structure reads correctly, while the HTML source tells you exactly what will be inserted into the CMS. It is also a convenient way to spot a broken link or an unclosed fence before publishing, without installing a static site generator or running a build step for a single paragraph.
How to use it in three steps
- Type or paste Markdown into the left box. The preview updates as you type, so structural mistakes show up immediately.
- Switch the right panel between Preview and HTML source. Read the preview for readability, then the source for the exact tags your target will receive.
- Press Copy HTML and paste it into your CMS, README or email template. Check how the destination handles code blocks, since some editors strip or restyle them. Test one heading, one list and one code block before pasting a long document into a content management system.
Questions people ask
Does it support tables and footnotes?
The converter covers the common core: headings, emphasis, lists, links, code, blockquotes and horizontal rules. Extended syntax such as tables and footnotes is not guaranteed, so check those parts in the HTML source before relying on them.
Will the HTML keep my custom classes or attributes?
No. The output is clean standard markup from the Markdown structure. Add site-specific classes in the destination editor or template after pasting.
Is the generated HTML safe to publish from untrusted input?
Treat pasted content as untrusted in any publishing pipeline. This tool is for your own drafts; a server that accepts Markdown from users still needs to sanitise the resulting HTML.
Will my links keep their target attributes?
The converter produces standard anchor tags with the href you wrote. Attributes such as target, rel and class are not part of Markdown's basic syntax, so add them in the destination template if your publishing system requires them.
Privacy: Markdown is turned into HTML and rendered in this browser tab by local JavaScript, so unpublished drafts, internal documentation and client copy are never transmitted, logged or stored anywhere.
How to use it
- Type or paste Markdown into the left box — the preview updates as you type.
- Switch the right panel between Preview and HTML source.
- Press Copy HTML to take the markup with you.
Why it stays private
Markdown drafts are frequently unpublished work: blog posts, documentation, release notes. Conversion happens in the page with plain text processing, so the draft is never transmitted or stored anywhere else.
Questions
Which Markdown features are supported?
Headings (# to ######), paragraphs, **bold**, *italic*, `inline code`, fenced code blocks, bulleted and numbered lists, [links](url), blockquotes and horizontal rules. The output is clean, semantic HTML without extra classes or inline styles.
Is the HTML safe to paste into my site?
The input is escaped before conversion, so any raw HTML you paste shows up as visible text rather than being executed. The output contains only the tags the converter itself generates.
Does it convert HTML back to Markdown?
No, this tool goes one way. A Markdown source is the better thing to keep anyway — it is easier to edit and can be converted again at any time.
