If it is blurred at its intended size, zooming in will only make it worse.

I think one would be zooming in on the webpage as a whole.  Users of
screen enlargers such as Big Shot zoom the entire window.  When zooming,
there are many associated problems with bitmapped pictures just being one.
 Another is fixed table size as opposed to relative table size.  if the
table is set to fixed dimensions, the more one zooms, the greater the
whitespace and the more one has to scroll.  With a large amount of
panning, users often become disoriented.  Using relative fonts may work on
the content of the webpage, but many with low vision need the applications
to be enlarged as well which lead to screen enlargers.
