## What is PDF Shrink?

PDF Compressor is a fully offline PDF compression tool. PDF processing runs on your iPhone, and documents are never uploaded to a server.

• One-tap compress: import a PDF from Files, Photos, or another app and shrink it fast.
• Three levels: Smaller for printing, Balanced for everyday sharing, Extreme for email and the web.
• Before/after comparison: see exactly how much space you saved.
• History: re-share or export previously compressed files anytime.
• One-time purchase: unlock multi-file batch compression — no subscription, no ads, yours forever.

PDF processing stays on device, and document contents and names are never collected.
