ARI is the RAW format used by ARRI Alexa cinema cameras, storing unprocessed sensor data from individual frames captured during film and television production. When a single frame needs to be pulled for a reference still, storyboard, or VFX plate without losing any quality, PNG is the better target than JPG, since it preserves the full dynamic range of the demosaiced frame without introducing any lossy compression artifacts.
Converting ARI to PNG is the practical choice when production stills need to retain maximum fidelity for further compositing or review work outside the main color-grading pipeline.
- Install Batchify Raw Image Converter on your Windows PC.
- Open the app and select Batch Mode for multiple frames, or Individual Mode for a single ARI file.
- Drag your ARI files or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to ARI and the "To" format to PNG.
- Click Convert. Lossless PNG files are written to your output folder, fully offline.
- Native support for ARRI Alexa's ARI cinema RAW format
- Lossless PNG output preserves full frame detail for VFX or review
- Bulk-convert multiple frames or stills in one batch
- Runs fully offline, keeping unreleased production footage private
- Multi-core processing for fast handling of large cinema frame files
Why choose PNG instead of JPG for a production still?
PNG avoids lossy compression entirely, which matters when a pulled frame needs to retain maximum quality for compositing, VFX reference, or archival purposes.
What kind of camera produces ARI files?
ARI is the native RAW frame format for ARRI Alexa cinema cameras, widely used in film and television production.
Can I convert multiple frames at once?
Yes, Batch Mode processes an entire folder of ARI files in one pass, including nested sub-folders if recursive scanning is enabled.
