Understand what counts as a duplicate
An exact duplicate is another copy of the same image or video. A similar photo is a separate capture with nearly the same scene. Two portraits taken a second apart may look interchangeable in a thumbnail, yet one may have better focus or expression.
That distinction matters because exact duplicates can often be reviewed quickly, while similar photos need a visual comparison.
Begin with exact matches
- Open a duplicate group and confirm that the images show the same content.
- Check whether one file has edits, a different crop, or important metadata.
- Keep the version you want and add only the unwanted copies to the delete list.
- Repeat the process in small batches rather than selecting the entire library at once.
Review similar groups more carefully
For a group of similar shots, compare the details that matter to you:
- Sharpness around faces or the main subject
- Eyes open, natural expression, and useful framing
- Motion blur and accidental obstruction
- Whether an image is part of a burst or a meaningful sequence
If the best image is not obvious, keep more than one. You can compare them again later.
Use a temporary delete list
A review list separates selection from permanent action. After choosing unwanted copies, inspect the list again at a larger size. This catches accidental taps and makes it easier to notice if every photo from an event was selected.
Remember Recently Deleted
After iOS confirms a deletion, the items usually remain in Recently Deleted for Apple’s recovery period. This provides a recovery window, but those items may continue using storage. Empty the album only when you are certain the cleanup is correct.
Review duplicates in Swipesift
Swipesift provides separate duplicate and similar-photo views, then lets you review the complete delete selection before requesting deletion through iOS Photos. It never deletes photos automatically.
