PDF Export

PDF export produces a polished, typeset document suitable for archiving, printing, and formal submission. The output meets the PDF/A-4f standard — an archival-grade format that bundles accessibility requirements alongside long-term preservation guarantees.

What you get

• High-quality typesetting. Your note is rendered using LuaLaTeX via pandoc, the same toolchain used by academic publishers and technical writers. Text, spacing, and layout look professional without any configuration on your part.
• Native TikZ diagrams. Diagrams are compiled directly as TikZ vector graphics inside the PDF — not rasterized images. This means they stay perfectly sharp at any zoom level, from 50% to 800% and beyond.
• Rendered math. If your note contains mathematical notation, it renders as native LaTeX math — proper fractions, symbols, superscripts, and all.
• Accessible structure. The PDF includes document structure tags that enable screen reader navigation: headings, paragraphs, figures with alt text, lists, and tables are all tagged correctly.
• Self-contained file. PDF/A-4f requires that all fonts be embedded in the file, so it will look consistent on any device — no dependency on fonts being installed.

Best uses

PDF works best when you want a document that:

• Won't be edited further after distribution
• Needs to look consistent across all devices and printers
• Should meet archival or formal submission requirements
• Contains math or complex diagrams that need to render precisely

Accessibility compliance

PDF/A-4f incorporates the PDF/UA (Universal Accessibility) standard, which covers the technical requirements for screen reader compatibility. This includes tagged content structure, alt text for images, reading order, and embedded metadata.
