Why convert TIFF to HDR?

Introduced in 1986 by Aldus Corporation, TIFF was great for its time. But HDR (created in 1989 by Radiance / Greg Ward) offers lossless compression and 32-bit float – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.

Transparent areas will be filled with white background
