Why convert JP2 to HEIF?

HEIF isn't automatically 'better' than JP2 in every case – but for Apple devices — efficient storage, it's the clearer choice. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. It's a low-effort change with a disproportionately high payoff.

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