Find and remove duplicate photos on your Mac: fast, private, and completely on-device
Find and remove duplicate photos on your Mac: fast, private, and completely on-device. Spots identical files and visually similar shots that other tools miss.
Dupe Remover scans any folder you point it at and groups duplicates two ways:
IDENTICAL
Byte-for-byte SHA-256 comparison. Catches the same file copied, renamed, or moved between folders, even across years of backups and reorganizations. Fast and 100% reliable — but won't catch a photo that has been re-saved, resized, or edited, since one changed pixel makes it a different file.
SIMILAR
Apple's on-device Vision framework compares what photos actually look like, not how they're stored. Catches re-exported JPEGs, light edits, the same shot at different resolutions, screenshots of the same image, and more. A strictness slider lets you tune how visually close two photos have to be before they're grouped — from "almost identical only" to "include light variants."
PRIVACY YOU CAN VERIFY
• 100% on-device. Nothing is uploaded, ever.
• No network entitlements. The app literally cannot phone home — macOS will block it if it tries.
• Sandboxed. Only the folders you grant access to are touched.
• No analytics. No tracking. No account.
BUILT FOR SPEED
• Smart caching. Hashes and Vision feature prints are stored locally, so repeat scans of the same library finish in seconds.
• Parallelized scanning that scales to libraries with thousands of photos.
• Universal binary — native performance on both Apple Silicon and Intel Macs.
SAFE BY DEFAULT
• Selected duplicates go to the Trash, never permanently deleted. Change your mind, drag them back.
• One-click "Select all but first" auto-picks a single keeper per group, then you confirm the move.
• Reveal in Finder on any thumbnail so you can sanity-check before deleting.
Requires macOS 14 Sonoma or later.
