Document PDF Preview

Render a local PDF with Mozilla pdf.js (lazy-loaded from jsDelivr).

About this tool

Side-by-side source and preview for plain text, Markdown (same subset as Markdown Preview), inline/display math via KaTeX (CDN), Typst source (monospace), and a separate tab that renders a local PDF file using Mozilla pdf.js (CDN).

Notes

LaTeX is not a full TeX engine — stick to math fragments ($$ … $$ and $ … $ ).
For print-ready Typst PDFs use the Typst CLI or typst.app; this tool focuses on drafting and PDF viewing.
