Wrap a bitmap font in a sfnt (TrueType) wrapper

fonttosfnt [ options ] -o file.ttf [ -- ] font...

Wrap a bitmap font or a set of bitmap fonts in a sfnt (TrueType or OpenType) wrapper.


Be verbose.


Do not crop glyphs. This usually increases file size, but may sometimes yield a modest decrease in file size for small character cell fonts (terminal fonts).


Write byte-aligned glyph data. By default, unaligned data is written, which yields a smaller file size.


Do not reencode fonts. By default, fonts are reencoded to Unicode whenever possible.

-g n

Set the type of scalable glyphs that we write. If n is 0, no scalable glyphs are written; this is legal but confuses most current software. If n is 1, a single scalable glyph (the undefined glyph) is written; this is recommended, but triggers a bug in current versions of FreeType. If n is 2 (the default), a sufficiently high number of blank glyphs are written, which works with FreeType but increases file size.

-m n

Set the type of scalable metrics that we write. If n is 0, no scalable metrics are written, which may or may not be legal. If n is 1, full metrics for a single glyph are written, and only left sidebearing values are written for the other glyphs. If n is 2, scalable metrics for all glyphs are written, which increases file size and is not recommended. The default is 1.


End of options.

Some of the font-level values, notably sub- and superscript positions, are dummy values.

X(7), Xserver(1), Xft(3x). Fonts in X11.

The version of Fonttosfnt included in this X.Org Foundation release was originally written by Juliusz Chroboczek <> for the XFree86 project.
