Find anything

search by any metadata properties. The sidebar provides an overview by date, location, or file type. XMP, IPTC, EXIF, ID3, and other common metadata standards are supported.

Compare and sort

Compare photos and videos side‑by‑side, highlight the best items with ratings, tags, and flags, and prune the rest.

Edit and fix

Users can add or fix metadata like ratings, tags, and locations. Simple photo edits include resize, rotate, crop, and adjust color.

Never miss a file

Diffractor indicates when files are present in the collection. Useful when an old memory card turns up and it’s unclear whether those files are already saved.

Synchronize

Automatically synchronize the collection to a NAS or network drive. Synchronization can be bidirectional, allowing collaboration and syncing others’ changes.
