Microsoft Bitmap Font Format stores bitmap font data. These font files have the same MZ signature as Microsoft executables, but use a *.fon extension. The same extension and signature is used by Microsoft vector fonts, but the vector format is different enough to warrant its own page. Multiple font sizes can be stored in the same file. The format appears to have been created for Windows 2.0, although a similar bitmap font was used for Windows 1.0 which appears to be based on a bitmap font created by Bitstream.

Although the font format was designed for Windows, numerous DOS programs have made us of it over the years. The format was also often included in the Windows installer of later DOS games.
