Why convert TGA to HDR?

The main issue with TGA is lack of browser support. Converting to HDR fixes this by providing perfect pixel preservation with smaller files. 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
