What is Markdown?
Markdown is a lightweight plain-text formatting syntax — headings with #, bold with **text**, lists with -, and links with [text](url) — that gets converted into HTML for display. It's the format behind README files, GitHub comments, Slack messages, and countless static site generators, because it's easy to write and read even before it's rendered.
How to Convert Markdown to HTML
- Paste your Markdown. Type or paste Markdown-formatted text into the box.
- Check the preview. The rendered output updates instantly, showing exactly how it will look.
- Copy the HTML source. Switch to the HTML source panel and copy the generated markup, or download it as a file.
What's Supported
Standard Markdown formatting is supported — headings, bold, italic, links, images, ordered and unordered lists, blockquotes, and code blocks — plus GitHub Flavored Markdown extensions: tables, task lists (- [ ]), strikethrough (~~text~~), and automatic links. Raw HTML embedded in your Markdown passes through into the HTML source unchanged; the live preview sanitizes it first so nothing unsafe can run on this page.
Frequently Asked Questions
How do I convert Markdown to HTML?
Paste your Markdown into the box — the rendered preview and the raw HTML source both update instantly, with no button to click.
Does it support tables, task lists, and strikethrough?
Yes — GitHub Flavored Markdown extensions (tables, task lists, strikethrough, autolinks) are supported alongside standard Markdown formatting.
Is the live preview safe if I paste untrusted Markdown?
Yes — the preview is sanitized before rendering, so embedded scripts or event-handler attributes are stripped and can't run on this page. The copyable HTML source is the exact, unmodified conversion output.
Can I use raw HTML inside my Markdown?
Yes — Markdown allows embedded HTML tags, and they pass through into the HTML source unchanged. The live preview sanitizes anything unsafe before displaying it.
Can I copy just the HTML, not the preview?
Yes — switch to the "HTML source" tab and use the Copy button to copy the raw HTML.
Is my text uploaded anywhere?
No. Markdown is converted to HTML entirely in your browser — your text is never sent to CurePDF's servers.
Is the Markdown to HTML converter free?
Yes, with no account required and no limit on how much text you can convert.
Can I download the generated HTML?
Yes — click Download to save the HTML source as a .html file.
