Why this works better than "online Markdown to PDF" tools

Most online Markdown-to-PDF tools work like this:

  1. You upload your file to their server
  2. They run a headless browser (puppeteer, often slow) to render it
  3. They return the PDF — sometimes after embedding a watermark

We render the preview in your browser using react-markdown + rehype-highlight + KaTeX + Mermaid, then hand the rendered DOM to your browser's native print engine. The result:

  • Faster — no round trip, no server queue.
  • Private — your document never leaves your device.
  • Higher fidelity — your operating system's fonts and your browser's exact rendering are used.

When the print dialog opens:

  1. Choose Save as PDF (Chrome, Edge) or PDF (Safari, Firefox)
  2. Paper size: A4 or Letter depending on your region
  3. Margins: Default (or Custom 0.5"–0.75" for tighter layout)
  4. Scale: 90–100% — drop to 90% if a wide table is being cut off
  5. Background graphics: ON if you want filled blockquotes and code backgrounds
  6. Headers and footers: off for a clean document

Comparison: 5 ways to convert Markdown to PDF

We covered the full picture in our Markdown to PDF guide, but the short version is:

  1. Browser print (this tool) — fastest, free, private
  2. Pandoc — most control, requires CLI install
  3. VS Code + extensions — great if you already use VS Code
  4. Marp — best for presentations
  5. Cloud APIs — best for batch / programmatic use

Pick the one that fits your workflow. For 95% of single-document conversions, browser print is the sweet spot.

Privacy

Your Markdown never leaves your browser. We don't upload, store, log, or train on your content.

Frequently asked questions

Is the Markdown to PDF converter really free?
Yes. There's no signup, no usage cap, no watermark, no upload. Markdown Viewer is open source under the MIT license — you can also self-host it.
Does the PDF include syntax highlighting?
Yes. We use highlight.js for 150+ languages. Make sure 'Background graphics' is enabled in your browser's print dialog if you want colored backgrounds on code blocks.
Can I convert Markdown with math equations to PDF?
Yes. Inline math (`$...$`) and block math (`$$...$$`) are rendered with KaTeX and printed as crisp, selectable text in the PDF.
What about Mermaid diagrams?
Mermaid diagrams are rendered as SVG inline, which means they print at native resolution without rasterization. Open the editor, paste a fenced ```mermaid block, and export.
Why doesn't a code block fit on one page?
Set print scale to 90% in the print dialog, or wrap long lines manually in the source. Browser print engines respect CSS page breaks but can't reflow long code lines.
Can I add a custom header, footer, or watermark?
Use your browser's print dialog: headers and footers can be enabled there, and many browsers support custom CSS for `@page` rules if you fork the project.
