To be pedantic (a virtue :-), WGS84 is a family of specifications,,
which define not only the ellipsoid (same for all in the family,
thankfully), but also the position/orientation of coordinates and a
definition of orthometric height.  Included in this, perhaps implicitly
since it is not really about a particular datum, is transforming from
XYZ to LLh.  But, agreed that this list of components does not include a
projection to the plane.

The OP probably meant to say that the data is in the WGS84 Coordinate
Reference System, or that the project projection is WGS84 Web Mercator.

(I agree that the OP appears to need a consultant.)
