Batch Settings
Quality reduction ahead
ARW is lossless, meaning every bit of data is preserved. HEIC uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your ARW file may contain MakerNote metadata. HEIC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 14-bit → 10-bit
ARW stores up to 14 bits per channel, but HEIC supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIC lossy compression can produce blurring and occasional color shifts at high compression. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Your ARW file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Container's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIC supports it
The HEIC file is saved and ready for download
