What it does

Markdown is convenient for writing, but publishing often requires HTML. This tool pairs a syntax-highlighted editor with a live, styled preview so you can turn source text into a standalone HTML document while keeping PDF export one click away.

The editor renders only the visible part of large documents, while preview updates are briefly delayed as you type. That keeps editing responsive even when the source contains many lines.

Common uses

  • Paste README files, release notes, specifications, reports, or AI-generated Markdown into the editor.
  • Check headings, lists, tables, blockquotes, links, and code blocks in the live preview.
  • Download a standalone styled .html document, the original .md source, or an A4 PDF.

Watch outs

  • Raw HTML is sanitized before preview and export; unsafe tags and attributes are removed.
  • The downloaded document includes built-in reading styles, which you can edit after saving.
  • PDF export currently uses a bundled Latin font and is intended for English text; additional script fonts can be added in a future extension.
  • Remote images remain remote URLs in HTML and must stay available to display later.

Privacy

Markdown parsing, preview rendering, and file generation happen in your browser. Your document is not uploaded.

FAQ

Does the Markdown leave my browser?

No. Editing, rendering, sanitization, and downloads all happen locally in the browser.

Is the downloaded HTML a complete document?

Yes. It includes the doctype, language, character encoding, responsive viewport metadata, and standalone reading styles.

Can I also download a PDF?

Yes. Both the Markdown-to-HTML and Markdown-to-PDF routes expose the same Markdown, HTML, and PDF download controls.
