[Gimp-user] reduce resolution while retaining image size on computer

I think I may have figured out the answer. What I'm trying to do is the
equivalent of taking a screen grab of a 15mb tiff image, which turns it into a
obviously lower quality tiff image of the same dimensions. Is the equivalent of
achieving this with gimp to simply reduce the dimensions and then use the zoom
function to enlarge the smaller picture? Is that effectively what "Grab" does?

Thank you
