Why Papersmith

Built for developers
who care about output.

Most tools make you choose between convenience and quality. Papersmith is the only Markdown-to-PDF converter that gives you both — browser-based, zero setup, and rendered with a real headless Chrome engine so what you see is exactly what you get.

Zero setup. Open a tab and go.

No package managers, no LaTeX distributions, no local servers. Papersmith runs entirely in your browser — paste your Markdown and get a PDF in seconds.

no install required
Pixel-perfect output, every time.

PDFs are rendered by a headless Chrome engine — the same browser your readers use. CSS Grid, custom fonts, modern layouts, and colours all come through exactly as designed.

Chrome-rendered
Diagrams and math in the PDF.

Mermaid diagrams render as crisp SVGs and KaTeX equations typeset beautifully — both in the live preview and in the final PDF download.

Pro feature

Four professional PDF themes — switch in one click

  • Live preview updates instantly as you switch
  • Theme CSS passed directly to Puppeteer — what you see is what you get

Mermaid diagrams that actually render in PDFs

Write ```mermaid blocks in your Markdown. Papersmith renders them as SVG in the preview — and embeds the same crisp vector graphics in your PDF.

  • flowchart, sequenceDiagram, classDiagram, erDiagram, gantt, pie
  • Rendered client-side and then captured by Puppeteer
  • Fallback to raw code block if diagram has a syntax error

Pro feature

KaTeX math — inline and block equations

Write $...$ for inline and $$...$$ for display equations. Rendered by KaTeX — the fastest math renderer in the browser. No MathJax, no lag.

  • Covers 95% of standard LaTeX math notation
  • KaTeX CSS injected into the PDF — renders identically to preview
  • Perfect for students, researchers, and technical writers
Math rendering
$E = mc^2$
E = mc²
$$\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$
∫₀^∞ e^(−x²) dx = √π / 2
