Why convert DIB to HEIF?

Think of HEIF as the format DIB files graduate to once they need Apple devices — efficient storage. 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
