NAPS2 vs ScanPapyrus

NAPS2 is free, open-source software for scanning documents and saving them as PDF, TIFF, JPEG, or PNG. It runs on Windows, macOS, and Linux, and supports WIA and TWAIN drivers with flatbed or automatic document feeder scanners, including duplex scanning. Users can reorder, interleave, rotate, crop, deskew, and adjust scanned pages’ brightness and contrast. OCR makes scans searchable, supports more than 100 languages, and can add text recognition to imported PDFs. NAPS2 can share scanners across a local network using ESCL, including with compatible Android and iPhone apps, but it must remain running on the server for sharing to work. It can send email through Gmail and Outlook, with the email address and secure sending token kept on the user’s computer and sent only to the relevant provider. Optional developer tools include a command-line interface for automation and a .NET scanning library. The free plan has no ads or restrictions, though OCR results cannot be saved directly to a text file.

ScanPapyrus is Windows software for scanning documents, books, and printed photos. Batch scanning can capture the next page automatically after a user-set interval, while book mode splits a two-page spread into separate pages. Cleanup tools deskew scans, remove black edges, sharpen text, adjust contrast, crop edges, and whiten gray backgrounds. The software supports automatic document feeders and two-sided scanning, with compatible devices listed from Kyocera, Epson, Canon, HP, Brother, Samsung, Xerox, and Mustek. Online OCR services, including OCR Web Service and OCR Space, can produce searchable PDFs, Word files, or plain text; OCR requires an internet connection and service account. ScanPapyrus edits PDFs, DjVu, multi-page TIFF, and other images, then exports PDFs with password protection, layout controls, or specified-size compression. A restricted free version is available. Home License costs $19.90 as a one-time purchase; Commercial License costs $59.90 as a one-time purchase.
