Why convert JPEG to JP2?

Introduced in 1992 by JPEG Committee, JPEG was great for its time. But JP2 (created in 2000 by JPEG Committee) offers lossy/lossless compression and 48-bit – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
