Duplicate photos
Duplicate photos are copies of the same image or nearly identical versions of the same media. They are usually the lowest-risk cleanup category because one copy often adds no value.
Similar photos
Similar photos are different images that look related. They might be retakes from the same moment, burst-like sequences, travel shots with slight framing changes, or several photos of the same subject.
| Type | Example | Cleanup risk |
|---|---|---|
| Exact duplicate | The same photo saved twice. | Usually lower risk after review. |
| Near duplicate | Two versions with tiny edits or metadata differences. | Moderate. Check which version is better. |
| Similar photo | Five shots from the same moment. | Higher. Expression, focus, and context can matter. |
Why similar photos need review
A similar-photo group can contain the best picture and the worst picture from the same moment. Automatic deletion can make the wrong choice. A review-first workflow is safer because it lets you keep the photo with the right expression, sharpness, framing, or memory value.
How CleanLens approaches this
CleanLens helps group similar shots so you can review them faster. The product direction is simple: AI-assisted or smart detection can find candidates, but you make the final call.
Best rule: use automation to find the group, not to decide what memories are disposable.
