Gallerynizer
Clean photos.
Reclaim space.
Gallerynizer finds exact duplicates, blurry shots, and screenshots piling up in your library, then shrinks your biggest videos — all reviewed by you, all 100% on your iPhone.
Free · iOS 26 or later · No account required
Find what's actually wasting space
Every tool reviews before it removes anything — nothing is ever deleted automatically.
Exact Duplicates
Byte-for-byte identical photos and videos, verified with real file hashing — not just similar-looking guesses.
Similar Photos
Near-duplicate bursts grouped together with a suggested best shot — sharpest, best exposed, eyes open.
Blurry Photos
Out-of-focus shots found by real sharpness analysis, not a guess based on file size.
Screenshots & Documents
Every screenshot in one place, plus receipts and documents detected by on-device text analysis.
Large Videos
Re-encode to HEVC for a typical 40–60% size cut, using your iPhone's hardware encoder. Original kept until you say so.
Video Montage
Turn a long video into an auto-generated highlight reel — reviewed before it's ever saved.
Private by design, not by policy
Gallerynizer has no server, no account, and no analytics or tracking of any kind. Every scan runs entirely on your iPhone using Apple's own Vision and Core Image frameworks.
- Nothing ever leaves your iPhone — no photos, videos, or metadata are ever transmitted anywhere.
- Nothing is auto-deleted — every removal goes through iOS's own system confirmation.
- No third-party code — built only on Apple's own frameworks, nothing else.
