The fastest photo and video organizer for Windows
Diffractor is a fast, free Windows app that works directly with files on your PC and connected drives. Your collection is simply the folders you choose for Diffractor to index. The index makes search and possible-copy checks fast; your photos and videos stay in ordinary Windows folders and are not uploaded.
View everything
View photos and play videos or audio files without switching apps. It supports most formats, including RAW photos. No extra codecs needed. Wide panoramas sweep at full width, and 360° photos become a view you turn by dragging.
Find anything
Search by any metadata property, and by when a photo was taken rather than when its file was written. 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. Photo edits include crop, straighten, perspective, temperature, tint, and automatic color, straighten, and document corrections.
Browse before you import
Browse a camera card, external drive, or any folder without moving its files. Diffractor shows which items are already in your collection or may have a matching copy there. Use Import only when you want to copy or move files to a reviewed destination. They join the collection automatically when that destination is already a collection folder.
Synchronize to your own storage
Compare your collection with a NAS or network drive, then copy changes in either direction. Synchronization can delete files and is not a backup, so review the differences and options before applying them.
Download Diffractor for Windows
Recommended for Windows 10 and 11. The Microsoft Store installs Diffractor and keeps it up to date. Needs Windows 11 or 64-bit Windows 10 version 2004 or later.
For Windows 7 or later, including 32-bit Windows, and PCs without the Microsoft Store. Diffractor checks diffractor.com for updates to this edition and offers to install them.
Diffractor is free. The two editions install separately, each with its own settings and index, so you only need one. Already using the installer edition? It updates itself, so there is no need to switch.
The installer edition is also available as a zip file. It is not portable: settings are stored in the registry and the metadata cache in the user profile. Older versions and source code are available on GitHub. Diffractor is covered by Terms and an End User License Agreement.
Diffractor is available in English plus Czech, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, Russian, Turkish, Ukrainian, and Chinese. Translated by amazing volunteers.
