Diffractor
Diffractor organizes photos and videos on Windows, with local file control and playback support for photo, video, and audio formats.
About Diffractor
Diffractor is a photo and video organizer for Windows. It indexes local media folders, then offers unified playback of photo, video and audio formats including RAW, instant metadata search across tags, location and camera data, and place assignment derived from GPS coordinates with a map and timeline of visits. It can read and write XMP, IPTC, EXIF and ID3 metadata, detect duplicates that have been re-encoded, resized or rotated, compare items side by side, and perform basic editing such as resize, crop, rotate, perspective, color and straighten adjustments.
Media stays in local files rather than a hosted library, and bidirectional sync to NAS or network drives is available for backup and collaboration. The app is distributed as a standard Windows installer, a Microsoft Store MSIX package, or a portable ZIP. The homepage describes the software as requiring no cloud storage or subscriptions, but pricing is not stated in the directory data. An optional cloud backup, upload or external sync service would move copies of files outside the local machine.
