TransType

TransType can convert fonts between Mac and Windows, and between all major font formats: PostScript, TrueType and OpenType. TransType supports batch conversion so users can convert hundreds of fonts at a time, even directly from Stuffit (.sit) archives. With TransType Pro, you can convert your fonts into the new universal OpenType format with Unicode encoding to make them compatible with the newest versions of Adobe Creative Suite, Microsoft Office and Apple iWork. TransType Pro even automatically adds some OpenType typographic features such as ligatures or fractions!
