Why convert HDR to WBMP?

People often ask why bother converting HDR at all. The short answer: WBMP handles Legacy WAP mobile devices noticeably better. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Once you see the size or compatibility difference, going back rarely makes sense.
