Why convert HDR to PSD?

The main issue with HDR is lack of browser support. Converting to PSD fixes this by providing perfect pixel preservation with smaller files. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Think of it as future-proofing your files rather than just converting them.
