Why convert DNG to ICO?

Introduced in 2004 by Adobe, DNG was great for its time. But ICO (created in 1985 by Microsoft) offers lossless compression and 32-bit – a massive leap forward. Converting DNG RAW images to ICO 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.
