PDF Compressor & Optimizer - Make your PDFs smaller!

Safe, Private, and Lightning-Fast!
All PDF processing happens directly in your browser, ensuring your files never leave your device for maximum security. 🛡
Plus, Puffin.Tools is completely FREE and lets you process PDFs in BULK (handle multiple files at once).

Please bear in mind that PDF compression is not trivial. Double check if your compressed PDF is good enough for your needs.

Waiting for something great ...

Quick Instructions:

  1. Select the PDF files you want to optimize (or several of them!).
  2. Select a compression mode. If you choose "Custom", adjust the sliders accordingly.
  3. Click "Process PDF".
  4. Get your optimized PDFs!

Quick Tips:

  • Compression Modes: "Passthrough" applies only PDF‑level optimizations without re‑encoding images. "Light", "Medium", "Heavy", and "Ultra" are re-encoding images.
  • If you select "Custom", you can manually set the JPEG quality and downscaling factor.
  • Processing is quite fast, so feel free to experiment with different settings!
