NEW: Smart Auto-Keep picks the best duplicate to keep. Cross-format matching finds HEIC vs JPG duplicates other apps miss. 100% private on your Mac.
Your Mac is full of duplicate photos and videos you don't know about. Dup finds them — even when they have different file names, sizes, or formats. A 4K video and its compressed 720p copy? Found. A HEIC original and its JPG export? Caught. Not just exact copies — Dup sees what your files actually look like.
Most duplicate finders only match identical files. Dup analyzes the visual content of your photos and videos to find matches other apps can't see. That's why users find 10-50 GB of duplicates that other apps missed completely.
THREE TOOLS, ONE APP:
1. FIND DUPLICATES — Similar Photos & Videos:
- Scan iCloud Drive, Photos Library, and Google Drive
- Scan any folder, external drive, or USB storage
- See every duplicate group with file sizes and paths
- Compare duplicates side by side with thumbnail storyboards
- Smart Auto-Keep selects the best version based on quality, resolution, and date
- Cross-format matching — finds HEIC vs JPG and MOV vs MP4 duplicates
- Photo quality ratings help you keep the sharpest version
- Delete up to 250 MB of duplicates — no Pro required
2. REMOVE SOMEONE — Face Detection:
- On-device face detection finds every photo & video of a specific person
- Choose who to remove, review every match, delete them all
- Works across your entire media library — local and iCloud
- All processing happens on your Mac — faces are never uploaded anywhere
- Perfect for breakups, falling outs, or simply decluttering
3. CLEAN DEV CACHES — Reclaim SSD Space:
- Xcode DerivedData, npm/node_modules, Cargo target directories
- pip caches, Homebrew caches, and more
- See exactly how much space each cache uses
- One-click cleanup with safe defaults — review before you delete
HOW IT WORKS:
1. Drop a folder, click "Choose Folder", or scan cloud storage with one click
2. Dup scans and groups results automatically
3. Review, compare side by side, then click Delete
BUILT FOR ALL MEDIA:
Works with JPG, PNG, HEIC, GIF, MP4, MOV, AVI, MKV, and every common photo and video format. Dup bundles its own analysis tools — nothing extra to install.
WORKS EVERYWHERE:
Scan local folders, external hard drives, USB storage, iCloud Drive, Google Drive, and your Photos Library. Start a scan in the background and keep working — Dup notifies you when it's done.
100% PRIVATE:
Dup processes everything locally on your Mac. Your photos and videos are never uploaded anywhere. No account required, no data leaves your device.

What's new in Dup 2.2.11:
Paywall Reliability — Fixed an issue where some App Store users saw the wrong purchase flow on launch. In-app purchase, restore, and subscription options now appear exactly as expected.
Smoother Sign-in — Email verification on direct downloads is more reliable. No more spurious "code expired" errors on the first try.
Trial & Purchase Polish — Cleaner free-trial activation. The paywall closes properly after a successful upgrade and your Pro state is recognized right away.
Quieter Background — Reduced noisy debug alerts. Image-format edge cases no longer trigger error reports. Dup stays out of the way.
Reopen from the menu bar — Window > Dup (⌘1) brings the main window back anytime after closing it. Dup keeps the background monitor running when the window is hidden; quit fully with ⌘Q or "Quit Dup" in the menu bar icon.
Plus everything from Dup 2.2:
Background Monitor, improved — When new duplicates appear, Dup now greets you with a gentle sound and a toast, so you never miss a change. Run a monitored scan on demand instead of waiting for the next cycle.
Sound Effects — Subtle audio cues for scan start, scan complete, and background finds. Mute anytime in settings.
More Reliable Monitoring — Auto-start, toggling on and off, and result display all behave consistently now.
Smoother Auto-Updates — Fixed an issue that kept direct-download builds from installing the latest version.
Better Photo Library Scanning — More reliable access to iCloud and Photos Library assets.
Plus fixes to Remove Someone layout, the app badge count, and monitor paywall edge cases.
