## What is PDF Compressor?

PDF Compressor: Sign Scan helps you finish submission-ready PDF tasks on iPhone without sending private documents to a web service.

Compress PDFs to common upload limits, create PDFs from photos or document scans, add a visual signature, merge files in order, remove pages, and share or save a new copy.

Key features:
• Compress PDFs for forms, applications, school portals, invoices, and uploads
• Choose practical size targets such as 500KB, 1MB, 2MB, and 5MB
• Turn photos or scans into a clean PDF
• Sign PDFs with your finger or Apple Pencil
• Merge PDFs and keep files in the order you need
• Select or remove pages before sharing
• Save to Files or share through the iOS share sheet
• Work without an account

Privacy-first by design:
Your documents stay on your device unless you choose to share or save them somewhere else. The app does not require login, cloud upload, or analytics tracking for core PDF tools.

Free users get 3 successful PDF tasks per local calendar day. Pro Lifetime is a one-time purchase that unlocks unlimited daily tasks, merging 3 or more PDFs, and reusable signatures. No subscription or auto-renewal.
