Why convert ARW to HEIC?

A quick technical note: ARW uses 14-bit per channel while HEIC uses 10-bit HDR. That difference matters most when your use case involves iPhone photos — efficient storage. 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. For most practical purposes, HEIC simply removes a recurring headache.
