Hi,

a) how has you saved it. As JPEG, portable network graphics,
    in a notebook, as encapsulate postscript
b) the input images where JPEG, that mean lossy compressed by
    a typical ratio 1:50. Usualy one avoid lossy compression at all
    especial when you work/"image process" the images because every
    evening when you save you work the lossy compression will reduce
    the quality of the image. Lossy compression is optimized in
    a way that a human eye will not see it. Any computer algorithm
    that work with the images will make the artifacts visible.
c) save the last image of you processing chain a JPEG. But keep in
    mind lossy compression is the week version of "trash it"

Regards
   Jens
