DupFinder

DupFinder finds true duplicates — not "similar-looking" guesses. Every photo, video, and file is compared by its SHA-256 content fingerprint, so a match means the files are byte-for-byte identical, even when the names are different.

PHOTOS & VIDEOS
Scan your entire library, see duplicates grouped with thumbnails, keep the newest copy with one tap, and delete the rest safely — everything goes to Recently Deleted, recoverable for 30 days.

SIMILAR SHOTS
On-device visual analysis groups retakes, bursts, and near-identical photos. Adjustable sensitivity, instant re-grouping, and a swipe mode to review each shot full-screen.

SCREENSHOTS
iOS tags screenshots natively, so DupFinder lists them exactly — in a photo grid with one-tap selection and smart picks like "older than 1 month."

BLURRY PHOTOS
Every photo gets an on-device sharpness score. Review the blurriest first and clear them in bulk.

LARGE FILES
See your biggest photos and videos sorted by size, compress oversized videos, and convert Live Photos to stills — with an honest report of exactly what was saved.

DUPLICATE CONTACTS
Finds contacts that share a phone number, an email address, or a full name. Before every merge you see exactly which contact survives and what gets copied onto it. Nothing changes without your confirmation.

FILES & ICLOUD DRIVE
Pick any folder from the Files app and find duplicate documents, downloads, and media with the same exact-match engine. Preview any file before deciding.

PRIVATE BY DESIGN
DupFinder contains no networking code at all. No accounts, no analytics, no uploads — your files never leave your device. We show you the actual content hash of every duplicate group, so you can verify the match yourself. And we won't pretend to clear other apps' caches — no app can; ours tells you what actually works instead.

Transparent. Exact. Local.
