Why convert JP2 to ARW?

Want faster load times and lower bandwidth costs? Switch from JP2 to ARW. The difference is dramatic: lossy/lossless vs lossless RAW, 48-bit vs 14-bit per channel. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The technical reasoning aside, the real-world result is fewer format-related issues.
