SwiftPaper turns your iPhone into a private document scanner. ID cards, contracts, medical records — every scan is processed on your device and never uploaded to any server. No watermark, no account, no sign-up — just scan, enhance and share. ◆ BLAZING-FAST SCANNING Powered by Apple's system-grade document scanning engine: edges are detected and pages captured automatically, perspective-corrected the instant you shoot. Snap a whole stack in one go and drag to reorder. Scanning an open book? Split the spread into left and right pages with one tap. ◆ 4 ENHANCEMENT FILTERS Original, Grayscale, sharp Black & White and smart Enhance that whitens the page while keeping colors vivid. Fine-tune brightness and contrast per page. ◆ OFFLINE TEXT RECOGNITION (OCR) Recognize printed text in English and Chinese — completely offline. Copy everything, or export as a text file. Search your library by content, and jump to the exact text block on each page to copy just what you need. ◆ ID CARD & PASSPORT MODE Scan ID cards, driver's licenses, bank cards and passports. Front and back are merged onto a single A4 page automatically — no manual cropping needed. ◆ EXPORT YOUR WAY Save polished PDFs (fit / A4 / Letter, with a default-size option to skip the prompt), shrink large files with PDF compression, or protect sensitive documents with a password. Exports of 5 pages or fewer are free 3 times a day; larger exports take a quick rewarded video. ◆ YOUR LIBRARY, ORGANIZED Browse by folder, multi-select to move, merge or delete, switch between grid and list views, and sort by name, date or page count. ◆ PRIVATE BY DESIGN All processing happens on your device. No accounts, no tracking. Optional iCloud sync (off by default) keeps your library in your own private iCloud space across devices. Lock the app with Face ID. ◆ MADE TO STAY FREE No watermark on any export, ever. Only very large exports occasionally ask you to watch a short video. SwiftPaper Pro (one-time purchase) removes all limits — no subscriptions. Privacy: all scanning and OCR happen on your device, and no photo or recognised text ever leaves it. Only the advertising SDKs used in your region collect device identifiers, and only when ads are shown; see our privacy policy for details.
