Why convert ARW to HEIC?

Because ARW files use lossless RAW compression and 14-bit per channel, they are not ideal for iPhone photos — efficient storage. Converting them to HEIC (lossy, 10-bit HDR) solves this. Converting ARW RAW images to HEIC applies essential post-processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
