Why convert DIB to HDR?
Because DIB files use uncompressed compression and 24-bit, they are not ideal for High dynamic range photography. Converting them to HDR (lossless, 32-bit float) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
