Duplicate photos take up space because even though they appear to be the “same” image, each copy is stored as a separate file that uses up storage. For example, photos can be duplicated due to issues like cloud syncing problems, importing photos from multiple devices, or even conversions (such as converting a Live Photo into a still image without deleting the original) that leave two or more copies on your device[1][6].
There are several ways to find these duplicate photos. On iPhones, the built-in duplicates album in the Photos app helps by automatically grouping exact matches, though it might miss near-identical images that only differ slightly. To catch those, third-party apps like Clever Cleaner use smart algorithms to scan your entire library and flag both exact and similar copies[1][4].
On Android devices, duplicate photos are often created from multiple downloads or messaging app shares. Using the built-in options within Google Photos—for instance, its feature that groups similar images and lets you choose a “top pick”—or using file manager apps and dedicated third-party duplicate photo removers can help you identify and remove extra copies[5][6].
In cloud storage, duplicate images may arise from multiple uploads and syncs between different devices. Tools such as Duplicate Photo Cleaner let you scan locally synced folders from your cloud (like Google Drive, Dropbox, or iCloud) and effectively identify and remove any duplicate files, reducing space consumption and organizing your digital photo library[9].
