Sony A6400 RAW Files: Open, Cull & Edit .ARW Free

A popular vlogging and travel body thanks to its flip-up screen and real-time eye autofocus. Many owners mix short photo bursts with video clips in the same outing, so the stills folder is usually smaller relative to total footage. Fast triage of that stills folder is the main workflow need for this camera's typical user.

Editing A6400 files with imagic

imagic opens .ARW files from the Sony A6400 natively on Windows and macOS. Point it at a card or shoot folder and it builds previews, scores every frame for sharpness, closed eyes, and composition, and groups near-duplicate bursts — so a full shoot collapses to its keepers before you edit anything.

Processing runs through the bundled RawTherapee engine, entirely on your machine: batch-apply one look across the keepers and export JPEGs in a single pass. Nothing uploads, which matters at about 18-23 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
