BAY is the RAW format used by Casio digital cameras, storing unprocessed Bayer sensor data before it's been demosaiced into a viewable color image. When a lossless export matters more than minimizing file size — for archiving, further editing, or print work — PNG is the better target than JPG, since it preserves every bit of detail recovered from the sensor without introducing further compression loss.
Converting BAY to PNG demosaics the sensor data and writes a lossless file, making it the practical choice when a Casio RAW photo needs to retain full quality through an editing or archival workflow.

Why choose PNG instead of JPG for BAY exports?
PNG is lossless, making it the better choice when preserving every bit of detail matters more than minimizing file size.
