Why convert TIFF to ARW?

Think of ARW as the format TIFF files graduate to once they need Sony Alpha mirrorless photography. 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.
