App: Photo Deduplicator
Developer: Bjoern Goerke
Genres: Foto und Video, Dienst­programme

Photo Deduplicator is a free third-party utility for Apple macOS that takes photo files as input (like JPEG, PNG, GIF or RAW format files) and identifies byte-wise identical, time-wise related or time-wise and content-wise similar photo files. 

After grouping photo files based on the selected criteria, it allows you to mark photo files individually or automatically in bulk for removal. Removal means putting them into your Mac's trash bin or moving them to a selectable output folder.

The in-app purchase option does not add any additional capabilities to the already fully functional free-of-charge version, and is solely intended for voluntary donations to support the development and maintenance efforts through the app's author.
