Why convert PNG to HEIC?

Have you ever tried using a PNG image on a platform that doesn't support it? That's frustrating. By converting to HEIC, you get a universally compatible lossy file that works everywhere. 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
