Sift vs Apple Photos duplicates: which cleans your library better?
Apple Photos has a built-in Duplicates album, which is genuinely useful for exact copies. Sift goes further: it uses perceptual matching to catch bursts, edits and re-saves that are not identical files, and it also handles blurry shots and old screenshots. Here is when the built-in feature is enough and when Sift helps.

Where the built-in feature stops
The Photos Duplicates album catches near-identical items well, but a lot of library bloat is not exact copies: five-shot bursts, an edited version beside the original, or the same image re-saved at another size. Those need perceptual matching, which compares what images look like rather than their exact bytes.
The two extra wins
Sift also targets the other two space hogs the Photos app ignores: blurry shots (while sparing deliberate portrait background blur) and the thousands of old screenshots that quietly accumulate. Everything it removes goes to Recently Deleted, recoverable for about 30 days.
Frequently asked questions
Is Sift better than the Apple Photos duplicates feature?
They complement each other. The Photos Duplicates album handles exact copies. Sift adds perceptual matching for bursts, edits and re-saves, plus blur analysis and screenshot cleanup, which the built-in feature does not cover.
How do I remove blurry photos on a Mac?
Sift runs sharpness analysis that flags genuinely blurry shots while sparing deliberate portrait background blur, then lets you review before removing.
Will Sift delete photos permanently?
No. Sift groups likely duplicates for review rather than auto-deleting, and everything it removes goes to Recently Deleted, recoverable for about 30 days.
Does Sift upload my photos?
No. Sift runs entirely on-device, so your photo library never leaves your Mac.
