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.
