Every PDF tool in one tab.

SwissArmyPDF is a collection of 28 PDF tools, all 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. If a tool can't be done well in the browser, we don't ship a watered-down version just to fill a checkbox. The toolkit grows when we can do something properly.

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.
