Why convert JPEG to ARW?

Because JPEG files use lossy compression and 24-bit RGB, 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.
