Why convert JP2 to JPEG?

Because JP2 files use lossy/lossless compression and 48-bit, they are not ideal for Photos and web images. Converting them to JPEG (lossy, 24-bit RGB) 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.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
