Similar photos
Also known as: near-duplicate photos, lookalike photos, almost-identical photos
Similar photos are different frames of the same moment — retakes, bursts, and small variations of one shot — rather than exact copies. They quietly pile up because we shoot several versions to get one good frame, and the rest stay in the library.
- Different frames of one moment, not exact copies
- Need a human choice — keep the best, drop the rest
- iOS Photos finds duplicates but not similar shots
Similar vs duplicate
A duplicate is the very same image stored twice; a similar photo is a slightly different shot of the same scene — a blink, a reframe, or the next frame in a burst. That difference matters because duplicates are safe to remove automatically, while similar photos need a quick human choice about which one to keep.
Apple’s Photos app catches exact duplicates under Photos > Utilities > Duplicates, but it does not group near-identical shots. Finding and thinning out similar photos is where a dedicated cleaner saves the most time.
Why they add up
Most people shoot two or three versions of every meaningful photo and never delete the also-rans. Over a few years that habit can leave thousands of near-identical frames taking up real space, even though only one of each is worth keeping.
