What it does

Markdown is convenient for writing, but finished documents often need a portable format. This tool pairs a syntax-highlighted editor with a live, styled preview so you can move from source text to a shareable PDF or standalone HTML file without switching apps.

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 the original .md source, a standalone styled .html document, or an A4 PDF.

Watch outs

  • PDF export currently uses a bundled Latin font and is intended for English text; additional script fonts can be added in a future extension.
  • Very wide tables and long unbroken code lines wrap to fit the A4 page.
  • Raw HTML is sanitized before preview and export; unsafe tags and attributes are removed.
  • Remote images must allow browser access to appear reliably in a generated PDF.

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.

Can it handle large Markdown files?

Yes. The syntax-highlighted editor uses viewport rendering so only visible lines are drawn, and live preview work is debounced while you type.

Is the downloaded HTML a complete document?

Yes. The HTML download includes a document title, responsive viewport metadata, and standalone reading styles.
