NAPS2 vs XSane

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.

XSane is a graphical program for accessing scanners and other image acquisition devices through SANE. It can preview images and scan from devices such as flatbed scanners, with available hardware depending on the installed device and configuration. Its viewer, save, copy, fax, and mail modes cover several ways to handle an acquired image. Used on its own, XSane saves scans as PNM or converts them to JPEG, PNG, PS, or TIFF. It can also send an image to a printer or serve as a frontend to a fax program. XSane can be invoked through The GIMP to pass images there for further processing. SANE also includes a network protocol for accessing image acquisition devices over a network. The listed features include color management, gamma enhancement, and a histogram. XSane is free, requires a SANE-compatible scanner, and is listed for Linux and Windows. Its source description also names OS/2 and various Unix systems; package dependencies include SANE and GTK 2.
