Free up space in your photo library with decisions you can review. Dedup2 groups similar photos and videos, helps you choose what to keep, and compresses oversized originals to a size you choose.
FIND SIMILAR PHOTOS AND VIDEOS
Burst shots, retakes, and saved copies add up. Dedup2 uses Apple's on-device Vision frameworks to group visually similar photos, so you can compare them before deleting.
• Adjust matching sensitivity to suit your library
• Rank photos by face quality, aesthetics, sharpness, subject focus, and resolution — in the order you choose
• Use Auto selection as you scroll, or make your own choices; manually edited groups keep your selection
• Review favourite badges and use the delete confirmation's option to exclude favourites
• Compare similar videos, with optional Duration Match for clips of similar lengths
• Focus on a year or album, and exclude albums you want to skip
COMPRESS PHOTOS AND VIDEOS
Keep a smaller copy of media you still want. Inspect the original and compressed preview before saving, including synchronized video comparison.
• Photos: 12 or 24 MP, or a custom target from 2 to 100 MP; resized copies use efficient HEIF, with JPEG fallback
• Original mode: keep a photo's current edit and discard the stored pre-edit original in a flattened copy. Deleting the original removes the ability to revert that edit
• Videos: choose 720p, 1080p, or 4K
• Compare original and new specifications, estimated savings, and previously saved targets
• Save compressed copies first, then separately confirm whether to delete originals
• Preserve capture dates, locations, and supported metadata
• Share individual items or selected group members from Duplicates and Location to albums or other apps
• In Compress, share an original or saved compressed copy, or open a video in OfflineClipper to trim
FILL MISSING LOCATIONS
Give unlocated photos and videos a place on your map. Dedup2 suggests coordinates from another item taken nearby in time; review the donor, time gap, and map before applying.
• Choose a matching window from ±5 minutes to ±4 hours
• Filter by year or album; screenshots are excluded by default
• Restore location changes from in-app Edit History
PRIVATE PROCESSING, CLEAR CONTROL
No account or media uploads to Dedup2 servers. Detection, quality scoring, and compression run on your device. Optional iCloud analysis downloads items from your own iCloud Photos library, with Wi-Fi, cellular, or off controls. Map previews and place names use Apple services and send coordinates to Apple.
Nothing is deleted or changed without confirmation. Deleted media goes to Photos' Recently Deleted; storage may not be reclaimed until it is permanently removed. Review carefully before emptying Recently Deleted.
FREE DAILY USE AND PRO
The free tier includes 10 deletions, 10 compressions, and 10 location fills per local calendar day, with separate allowances. Dedup2 Pro removes these limits through a monthly auto-renewable subscription or one-time lifetime purchase. Eligible new subscribers may receive an introductory trial. Current local pricing and trial eligibility appear before purchase. Manage or cancel subscriptions in Apple Account settings; restore purchases in the app.
