Your files stay on your computer. Nothing is uploaded anywhere.

How does this work?

This tool loads your PDF right inside your browser, strips out unnecessary metadata and unused objects, re-encodes embedded images at a smaller size, and saves a leaner version. Your file never goes to a server -- the whole process happens on your device.
