Why convert HDR to JP2?

The main issue with HDR is lack of browser support. Converting to JP2 fixes this by providing broad compatibility across devices and software. 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 short, this is less about one format being 'better' and more about matching the tool to the job.
