Chroma subsampling in jpeg compression

Question

Is the chroma sub-sampling the first step to compress an image file to jpeg image file? Is this the step that we implement in Color Space Conversion?

Did you do any research? http://en.m.wikipedia.org/wiki/JPEG — Oliver Charlesworth, Nov 28 '14 at 08:45

Color space conversion takes place before sampling. Sub-sampling is the first step that compresses the image.
