Why convert PSD to HDR?

PSD served its purpose well, but modern workflows increasingly favor HDR for High dynamic range photography. 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. In practice, teams that make this switch rarely go back to PSD for this use case.

Transparent areas will be filled with white background
