Question

I have a cmyk pdf that I am trying to convert to a RGB jpeg or png file but have the colors stay pretty close to what the CMYK version is (compared to how photoshop does it)

Based on previous answers, I finally managed to keep natural colors from a CMYK pdf to a RGB png simply using:

convert -colorspace sRGB cmyk.pdf rbg.png
