Why convert JPEG to ARW?

If you work with JPEG regularly, you've probably hit compatibility walls. ARW was built for exactly this gap – 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. Most users notice the difference within the first few converted files.
