Why PDF Toolkit

Built for speed, privacy, and everyday use.

Lightning fast

Most operations finish in under 10 seconds — no upload wait, no server queue.

Truly private

Files are processed on your device using WebAssembly. Nothing is uploaded.

No signup, no interruptions

Bookmark it and use it every day. No accounts, no interruptions.

Security first

Your PDFs never leave your device.

Traditional online PDF tools upload your files to a server. That's slow and puts sensitive documents at risk. PDF Toolkit processes everything in your browser — contracts, invoices, medical records and personal docs stay on your machine.

  • Client-side processing with WebAssembly
  • No uploads, no telemetry, no tracking
  • Works offline after first visit
  • Open standards — no vendor lock-in
