Find duplicate photos on Mac in your browser
DupShelf helps Mac users deduplicate photo libraries stored on the internal SSD or external drives without installing heavy cleanup suites.
Use Chrome or Edge on macOS
Safari does not support full-folder picking for this workflow. Chrome and Edge on desktop provide folder access and optional move-to-folder.
Photos and exports
Clean duplicate exports from Lightroom, burst folders, and Downloads before you copy libraries to a NAS or Time Machine backup.
Questions
- Will this merge with Apple Photos?
- DupShelf scans folders you choose. It does not modify the Photos app library directly; point it at exported folders or a copied library if needed.
