Why convert HEIF to DNG?
Not all image formats age equally. HEIF (2015) predates many of today's requirements, while DNG directly addresses Universal RAW — open standard by Adobe. 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 technical reasoning aside, the real-world result is fewer format-related issues.
