PDF-PRO Studio

Turn your iPhone into a pro PDF studio. Read, annotate, merge, split, compress, OCR, sign and encrypt — all on-device, all private.

PDF-PRO is the all-in-one PDF studio for iPhone — read, annotate, merge, split, compress, OCR, sign and encrypt, all on your device.

Built natively with Apple's PDFKit, VisionKit, Vision, PencilKit and StoreKit 2, PDF-PRO pairs a modern iOS design with serious document power. Best of all, every operation runs locally and offline — your files never leave your device.

ORGANIZE • Merge multiple PDFs into one, or split a document into separate files • Reorder, rotate and delete pages with drag-and-drop • Convert photos and scans into clean, A4-sized PDFs

OCR TEXT EXTRACTION • Powered by Apple Vision — recognize text in multiple languages • Copy recognized text straight from any page

COMPRESS • Shrink large PDFs by up to 80% with Light / Standard / Deep presets • Perfect for email and messaging size limits
