Same video saved twice? Dup matches copies across 4K and 720p, MOV and MP4, HEIC and JPG, even when names differ. Compare, then delete. All on your Mac.
Dup finds duplicate videos and photos on your Mac, even when the copies have different names, sizes, resolutions or formats. A 4K original and its 720p re-encode are one video to Dup. So are a HEIC photo and its JPG export. Tools that only match identical files cannot see either pair.
Pick the folders, drives or Photos library to scan. Dup groups every set of copies, picks the one to keep, and lets you compare before anything is deleted. Everything you delete goes to the Trash first (photos go to Recently Deleted), so you can always undo.
SIX TOOLS, ONE APP:
1. FIND DUPLICATES (Videos & Photos):
- Duplicate videos matched across codecs (H.264, H.265, ProRes), resolutions (4K, 1080p, 720p) and containers (MOV, MP4, MKV)
- Cross-format matching finds HEIC vs JPG and MOV vs MP4 duplicates
- Scan your Photos library, iCloud Drive, and the cloud folders you choose (Google Drive, Dropbox, OneDrive)
- Scan any folder, external drive, or USB storage
- See every duplicate group with file sizes and locations
- Compare two copies with a wipe: drag the seam across them, frame by frame for videos, with zoom
- Dup picks the best copy to keep by resolution, size and date
- Deep Scan (Pro) uses on-device AI to find near-identical shots
- Smart Select (Pro) lets you set the rules: resolution, file size, newest or oldest
- Delete up to 250 MB of duplicates, no Pro required
2. REMOVE SOMEONE (Face Detection):
- On-device face detection finds every photo and video of a specific person
- Choose who to remove, review every match, delete them all
- Works across your entire media library, local and iCloud
- Faces are never uploaded anywhere
3. PHOTO QUALITY SCAN (Blurry, Dark, Overexposed and Tiny Photos):
- Flags photos that are blurry, too dark, overexposed or too small to keep
- Groups them by issue so you can clear them in one pass
- All analysis runs on your Mac
4. DUPLICATE MONITOR (Pro):
- Rescans the folders you choose hourly, daily, or weekly
- Notifies you the moment new duplicate photos or videos appear
- Runs quietly in the background while you keep working
5. CLEAN CACHES (Reclaim SSD Space):
- Browser caches for Chrome, Brave, Edge, Arc, Firefox and more
- Xcode DerivedData, npm/node_modules, Cargo target directories
- pip caches, Homebrew caches, and more
- See exactly how much space each cache uses, and review it before you delete
6. FIND FORGOTTEN FILES (Reclaim Hidden Storage):
- Surface big files you forgot existed, like old DMGs, screen recordings, abandoned ZIPs
- "Safe to delete" badges when a forgotten file also has a duplicate elsewhere
- Smart defaults (1 MB+, untouched for 30+ days), fully tunable
- Works on Downloads, Documents, Desktop, external drives, anywhere
BUILT FOR ALL MEDIA:
Works with JPG, PNG, HEIC, GIF, MP4, MOV, AVI, MKV, and every common photo and video format, with nothing extra to install.
WORKS EVERYWHERE:
Scan local folders, external hard drives, USB storage, iCloud Drive, the cloud folders you choose, and your Photos library. Start a scan in the background and keep working. Dup can notify you when it's done.
PRIVATE BY DESIGN:
Your photos and videos never leave your Mac. Scanning, matching and face detection all run locally, and no account is required. Anonymous crash reports and usage statistics never include your files or file names.
DUP PRO:
Free covers scanning, comparing, and up to 250 MB of cleanup. Dup Pro adds unlimited cleanup, Deep Scan, Smart Select, and Duplicate Monitor. Choose an annual subscription at $29.99/year with a 7-day free trial, or a one-time purchase of $39.99 that never renews. Payment is charged to your Apple Account when the trial ends. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it anytime in the App Store, under Subscriptions in your account settings.

What's new in Dup 3.3.5:
Safer cleanups: A file you moved or deleted after a scan now leaves your selection, and if the copy you were keeping is gone, Dup keeps the best copy still on your disk.
Fewer false matches: Videos with almost no motion, such as black clips and quiet screen recordings, are no longer grouped as duplicates of each other unless they are exact copies.
Clearer folder choices: Pick your whole startup disk and Dup scans your home folder, where your own files are. A folder that belongs to macOS is explained when you pick it, instead of failing the scan.
Pro recognized on macOS 27: Your Dup Pro purchase is now recognized reliably on the latest macOS, and the count of copies marked for cleanup always adds up.
