Why convert DNG to DDS?

The main issue with DNG is lack of browser support. Converting to DDS fixes this by providing broad compatibility across devices and software. Converting DNG RAW images to DDS applies essential post‑processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software.
