The Free On-line Dictionary of Computing (30 December 2018):

zoom

    To show a smaller area of an image at a higher
   magnification ("zoom in") or a larger area at a lower
   magnification ("zoom out"), as though using a zoom lense on a
   camera.

   Unlike in an optical system, zooming in on a computer image
   does not necessarily increase the amount of detail displayed
   since this is limited by what is actually stored in the image.
   Similarly, you cannot zoom out beyond the full size of the
   image.
