Why convert HEIF to ARW?

People often ask why bother converting HEIF at all. The short answer: ARW handles Sony Alpha mirrorless photography noticeably better. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Once you see the size or compatibility difference, going back rarely makes sense.
