Find Duplicate Images Using Perceptual Hashing
Drop a batch of images and the tool identifies duplicates and near-duplicates using perceptual hashing. It catches copies even if they've been resized or slightly edited.
Useful for cleaning up photo libraries, deduplicating product image catalogs, or finding reposted content. Much smarter than just comparing file sizes — it actually looks at what's in the image.
