Why convert ICO to DNG?

ICO served its purpose well, but modern workflows increasingly favor DNG for Universal RAW — open standard by Adobe. 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.
