NAPS2 is a free GPL-2.0-or-later scanning app. Hardware, local storage and backups are separate costs. The current platform documentation supersedes the README’s older minimum versions: macOS 12+; Linux GTK 3.20+, glibc 2.31+ and libsane. Linux Flatpak does not support third-party SANE drivers. OCR adds searchable text to scans; it is not a full PDF text editor. See the provider privacy policy before connecting email services.
