In general for fonts, using bitmapped image formats are not the best way
to go since they cannot result in "smooth" curves.

Depending upon how you plan to actually use the images, PS/EPS/PDF
vector based image formats would yield higher quality images and fonts.

Be aware also that bitmapped images do not resize well, which is another
limitation of that format.
