Every PDF tool in one tab.

SwissArmyPDF is a collection of 39 PDF tools — 22 of them already running entirely in your browser, no upload required. Built because the existing PDF sites either upload your files, paywall the good tools, or splatter ads across every step.

The principles

• +
  Local-first. When a tool can run client-side, it does. Your files stay on your device.
• +
  Free, no watermark. Output is yours, clean, unbranded.
• +
  Fast. No upload round-trip. A 100-page PDF takes under a second to merge or split on a modern laptop.
• +
  Honest about limits. Tools that genuinely need a server (OCR, AI, full Office conversions) are labeled as such. We don't ship a worse browser-side stand-in just to fill a checkbox.

The stack

Astro for the static site, Tailwind for styles, pdf-lib for PDF generation, pdfjs-dist for rendering. Everything ships as static HTML / JS / WASM — no servers needed for the LIVE tools.
