| Format pliku G2F jest przeznaczony dla programu [[Graph2Font]]. Autor z lenistwa uprościł go maksymalnie, przez co objętość plików G2F jest dosyć spora, średnio 160 kB. Duża objętość i podatność na kompresję wynika głównie z tego, że jest to zrzut pamięci zarezerwowanej na tablice używane przez G2F. W ostatnich wersjach programu umożliwiona została kompresja plików G2F.

| Pliki kompresowane są przy pomocy ogólnie dostępnej biblioteki ZLIB, posiadają wówczas nagłówek G2FZLIB.
