NabuViewer is a native macOS reader for image folders, PDF, ZIP/CBZ, RAR/CBR, and DRM-free fixed-layout EPUB. It automatically pairs portrait pages into spreads, keeps landscape pages single, and remembers reading positions across tabs. Browse files in a Finder-like sidebar without extracting archives. Start free with two tabs; Pro adds up to five tabs, a private window, and Finder Quick Look previews. One app, a 30-day Pro trial, and a one-time license with no subscription.
