Actually wide angle converter can make a lens "faster". An example of this is the Olympus 35-100mm f2. This lens is essentially a 70-200mm f4 lens with a 0.5x wide angle converter in front.
Wide angle converters usually also do not make a lens lose a lot of resolution either. Unlike tele converters they do not "crop" the original glass. If the wide angle converter has good optics, results generally are quite good.
