Is there a good iOS app that can batch scan documents and convert them to PDFs without adding watermarks?

PDFMaker is an iOS application that excels at transforming physical documents into digital PDFs, particularly for batch scanning tasks without intrusive watermarks. It addresses common needs such as digitizing stacks of receipts for expense tracking, archiving legal paperwork, or compiling lecture notes. The app's camera scanner automatically detects document edges and optimizes image quality, reducing shadows and improving contrast. Users can scan multiple pages in a single session, with the option to reorder or delete pages before finalizing the PDF. Features like optical character recognition enable searchable PDFs, though this may be a premium add-on. The export process is streamlined, allowing saves to local storage or direct upload to cloud services like Google Drive or OneDrive. Feedback from users highlights the app's reliability in producing clean, professional-looking PDFs, with many appreciating the lack of watermarks that often plague free alternatives. On the downside, some reports mention that the OCR accuracy can vary with handwriting or poor-quality prints, and the interface might feel slightly cluttered during initial use. Additionally, while the core scanning is free, unlocking unlimited batch scans and advanced editing tools requires a one-time purchase or subscription. For anyone regularly handling document digitization on an iPhone, PDFMaker offers a robust set of tools that justify its rating, though it's wise to test the free version first for specific needs.
