Why convert ICO to ARW?

Because ICO files use lossless compression and 32-bit, they are not ideal for Sony Alpha mirrorless photography. Converting them to ARW (lossless RAW, 14-bit per channel) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
