Convert Markdown into clean HTML
Markdown to HTML turns notes, README content, docs, changelogs, release notes, and CMS drafts into semantic HTML that you can copy or download. The live preview helps you check headings, lists, code blocks, links, and tables before using the output in a website or publishing workflow.
Need the reverse direction? Use the HTML to Markdown converter to turn rendered HTML, CMS exports, or scraped pages back into portable Markdown.
1. Markdown Input
This is where you write or import source Markdown before conversion.
- Editor. Paste or write Markdown with headings, emphasis, links, lists, blockquotes, tables, and fenced code blocks. The preview updates as you type.
- Open. Loads a local .md, .markdown, or .txt file up to 2 MB. The file is read in the browser and never uploaded.
- Copy MD. Copies the current Markdown source so you can move the original content into another editor.
- Clear. Empties the editor while leaving your conversion options unchanged.
- Stats. Shows line, word, source character, and generated HTML character counts for quick publishing checks.
2. HTML Preview
The preview renders the converted HTML so you can catch formatting problems before export.
- Theme. Switch between dark, light, GitHub-style, and reader-style previews. This changes preview appearance only; exported HTML remains controlled by the export mode.
- Refresh theme. Quickly toggles between dark and light preview modes.
- Expand preview. Opens a larger preview overlay for checking long documents, tables, and code blocks.
- Safe preview. The on-screen preview is sanitized to avoid risky HTML execution while still showing normal Markdown output.
3. Options
- GitHub Flavored Markdown. Enables common README features such as tables, task lists, strikethrough, and fenced code blocks.
- Line Breaks. Converts single newline characters to HTML line breaks. Use it for plain text notes; leave it off for standard Markdown paragraphs.
- Allow Markdown HTML. Lets inline HTML from the source pass into the parser. Disable it when you want angle-bracket HTML to appear as text.
- Sanitize Output. Removes unsafe tags, event handlers, and risky attributes from copied or downloaded HTML. Keep this enabled for content from untrusted sources.
4. Export HTML
- HTML Fragment. Outputs only the converted body HTML. Use it for CMS fields, component slots, emails, docs systems, and existing templates.
- Full HTML Document. Wraps the output in doctype, head metadata, responsive viewport, and a minimal stylesheet so the file can open directly in a browser.
- Copy HTML. Places the selected output mode on your clipboard.
- Download HTML. Saves the result as an .html file using the selected export mode.
- Reset All. Restores the sample Markdown and default production-safe settings.
Production tips
Keep sanitization enabled when converting Markdown from users, comments, or external sources. Use HTML Fragment when pasting into an existing design system, and Full HTML Document when you need a standalone file for review, handoff, or quick publishing. To round-trip an existing site export, run the HTML through HTML to Markdown, edit the result, then bring it back here.
