Why convert HDR to GIF?

Want faster load times and lower bandwidth costs? Switch from HDR to GIF. The difference is dramatic: lossless vs lossless, 32-bit float vs 8-bit. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. This is one of those changes that pays for itself almost immediately.
