What's the best iOS app for scanning and converting my paper documents into PDFs I can search?

Photo Scan & Converter To PDF is a straightforward tool for creating organized, searchable PDFs from physical documents using an iPhone's camera. The app stands out for its robust OCR (Optical Character Recognition) engine, which converts photographed text into selectable and searchable data within the final PDF file. This feature is particularly valuable for digitizing receipts, contracts, or handwritten notes that need to be referenced later. The app automatically detects page edges, corrects perspective, and enhances contrast to produce a clean, scanner-like result. Users can then combine multiple scans into a single multi-page PDF, add password protection, and export directly to cloud services like iCloud Drive or Google Drive. While the interface is functional, some user reviews indicate the free version includes watermarks and has export limitations, nudging users toward the one-time purchase pro upgrade for unlimited use. For students archiving notes or professionals needing to digitize client paperwork quickly, the app provides a reliable, purpose-built solution that focuses on the core task without unnecessary features. The text recognition accuracy is generally high on printed documents, though performance can vary with poor lighting or highly stylized fonts.
