Why convert DDS to HEIF?

DDS served its purpose well, but modern workflows increasingly favor HEIF for Apple devices — 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. The conversion itself takes seconds — the benefits last much longer.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
This format requires a WebAssembly decoder — allow a moment for library loading
