Is it free to compress a PDF?

Do you upload my files?
No. The tool runs inside your browser using WebAssembly. Your file never leaves your device, and it still works with Wi-Fi turned off.
Does it work on my phone?

Why did my file barely shrink?
Files made from text are often already small. Scans and photos shrink the most. Try a stronger mode or Compress to size.
