PhotoSweep - Duplicate Photo Finder

PhotoSweep uses smart perceptual hashing (aHash/dHash/pHash) to detect visually similar duplicate photos, including near-identical shots, recompressed versions, and cropped edits, rather than just matching file names. It features automatic duplicate grouping, multi-folder scanning, and quarantine cleanup for safe restores, all while working offline to ensure full privacy. It is available on a pay-what-you-want basis.
