Frequently Asked Questions

How does browser-side PDF compression work?
The tool loads your PDF into browser memory via pdf-lib, strips duplicate metadata dictionaries, compresses raw font tables and cross-reference streams, and optimizes page content streams for minimal byte footprint.
Can I compress images and photos here too?
Yes. If you upload an image (PNG, JPG, WebP), the tool quantizes color palettes and applies WebAssembly compression algorithms to shrink the file.
