Why convert TGA to HDR?

Compatibility, file size, and quality rarely align perfectly – HDR gets closer to that balance than TGA for High dynamic range photography. 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.

Transparent areas will be filled with white background
