hi no it dosent change the dimensions.

im currently still investigating details but in all files the changes are present.

i extracted the DIFF of the image changes and you can see them attached.

if you look at the compare.jpg you will see the Quality settings changing from 75% --> 92% so it seems calibre is doing a preprocessing of the files before rewriting them.

Thanks

Joe
