Dupless cleans up your photo library the private way — right on your device. It finds duplicate and near-identical shots, picks the best one in each set, and helps you safely remove the rest. No account, no cloud, and your photos are never uploaded. WHY DUPLESS • Private by design — your photos are analyzed right on your iPhone or iPad and never leave your device. • Nothing is deleted automatically. You review every group, and removed photos go to Recently Deleted, so they're always recoverable. • Fast, on-device analysis powered by Apple's Vision framework. FIND WHAT'S REDUNDANT • Detects exact duplicates and visually similar shots using on-device perceptual hashing and Apple's Vision framework. • Groups a same-scene series — like a "Happy Birthday" portrait burst — and pre-selects everything but the keeper. • Shows a match percentage so you can see why photos were grouped. KEEP THE BEST SHOT • Automatically ranks each group by sharpness, exposure, and resolution to recommend the keeper. • Tap "Why this one?" for a plain-language explanation of the pick. • Protects your favorites, edited photos, Live Photos, hidden, shared, and photos with people. REVIEW WITH CONFIDENCE • Swipe through groups, adjust what's selected, and move only what you choose to Recently Deleted. • Browse your library and revisit past results anytime. SIRI & SHORTCUTS • Start scans, review groups, and build a best-shots album by voice. Made for iPhone and iPad — reclaim space and tidy your library, on your terms.
