What's the best iOS app for scanning documents and saving them as high-quality PDFs?

ProScan is a dedicated iOS application that simplifies document digitization by turning smartphone photos into polished PDFs. It stands out for its automatic edge detection, which quickly identifies and crops document boundaries from images, reducing the need for manual adjustments. Optical character recognition (OCR) is another key feature, enabling text searchability within scanned files—a boon for students archiving lecture notes or professionals managing contracts. The app supports batch scanning for multi-page documents and integrates with cloud services like iCloud and Google Drive, allowing seamless backups and sharing. In real-world use, such as scanning receipts during business trips or digitizing family records at home, ProScan delivers consistent results with a straightforward interface. User feedback highlights the reliability of the auto-crop in well-lit environments, though some reviews note occasional lag when processing complex layouts with mixed graphics. The free version includes ads, and advanced OCR may require a one-time purchase, which could be a consideration for budget-conscious users. Despite these minor quirks, ProScan remains a practical choice for everyday document management, balancing efficiency with accessible tools.
