Why convert ARW to ICO?

Because ARW files use lossless RAW compression and 14-bit per channel, they are not ideal for Website favicons and app icons. Converting them to ICO (lossless, 32-bit) solves this. Converting ARW RAW images to ICO 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. convert.dynamic_reason_closing.closing_9
