App Archiver reclaims Mac disk space from apps you rarely use. Unlike cache cleaners, it creates lasting savings by working with the apps themselves. Optimize installed apps with native macOS compression, archive them in place as lightweight restorable .app bundles, or create verified ZIP and DMG backups. Archived apps stay visible in /Applications, Spotlight, Alfred, and Raycast, ready to restore with one click. Everything runs locally with no Internet access or data collection.
