Why convert PNG to HEIF?

The main issue with PNG is incompatibility with most modern applications. Converting to HEIF fixes this by providing stunning high dynamic range colors. 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
