Why convert PNG to HEIC?

PNG served its purpose well, but modern workflows increasingly favor HEIC for iPhone photos — efficient storage. The shift is worth making. 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 worth doing once properly rather than repeatedly fighting PNG limitations.

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