How to Delete Duplicate and Blurry Photos in iOS 12

Managing photo storage in iOS 12 relies on a combination of system storage recommendations, camera curation features, and manual search tools. While newer iOS versions include automated duplicate detection, iOS 12 does not feature a dedicated native tool specifically designed to scan your library and automatically delete duplicate or blurry photos. Instead, it suggests general storage cleanups through system settings, provides tools to cull redundant shots taken in Burst mode, and relies on smart search indexing to help users manually locate and delete unwanted pictures.

iPhone Storage Recommendations

iOS 12 provides automated storage management suggestions through the device settings rather than the Photos app itself.

To view these suggestions:

  1. Open Settings.
  2. Tap General, then select iPhone Storage.
  3. Under the Recommendations section, iOS 12 will suggest actions based on your usage, such as:
    • Optimize Photos: Automatically uploads full-resolution photos and videos to iCloud while keeping smaller, device-sized versions on your phone.
    • Empty "Recently Deleted" Album: Prompts you to permanently purge photos you previously deleted that are still occupying local storage.
    • Review Large Attachments: Directs you to media files sent via Messages that consume significant space.

Managing Duplicates and Blurry Shots with Burst Mode

The closest native mechanism iOS 12 has for identifying and removing duplicate or blurry shots is found in Burst Mode. When you take a series of rapid-fire photos, the iOS 12 machine learning algorithm analyzes the sequence to identify closed eyes, blurriness, and poor framing.

To clean up burst photos:

  1. Open the Photos app and navigate to Albums > Bursts.
  2. Select a burst sequence and tap Select... at the bottom of the screen.
  3. iOS 12 automatically places a gray indicator dot under the thumbnails of the sharpest, best-composed shots.
  4. Check the box for the photo(s) you wish to keep and tap Done.
  5. Select Keep Only [Number] Favorite(s). iOS 12 will delete the remaining duplicate and blurry frames immediately.

Using Search to Manually Locate Similar Images

iOS 12 introduced an upgraded search infrastructure using on-device machine learning that indexes images by objects, scenes, and locations.

To locate duplicate or redundant photos manually:

  1. Open the Photos app and tap the Search tab.
  2. Search by specific terms, such as a location (e.g., "Paris"), a date, or an object (e.g., "dog" or "sunset").
  3. Multiple search terms can be combined to narrow down exact events.
  4. Tap See All to scan through clusters of photos from the same event, select duplicate or low-quality shots, and tap the Trash icon.

Third-Party Alternatives for iOS 12

Because iOS 12 lacks an automated, library-wide scanner for non-burst duplicates and general out-of-focus photos (a feature formally introduced in iOS 16 with the "Duplicates" album), users on iOS 12 typically rely on third-party cleaner utilities from the App Store. Apps designed for storage management scan the library via local device permissions to detect identical file hashes, similar compositions, and blurry images, grouping them together for quick batch deletion.
