Description
The .fon format is a Windows font resource file that stores bitmap (raster) fonts or acts as a container referencing font data for use by older Windows applications. It is commonly used for legacy screen fonts, especially fixed-size bitmap fonts used in older Windows GUI elements and MS-DOS era applications. Modern Windows systems retain support for .fon files mainly for backward compatibility with legacy software.
SFD (Spline Font Database) is the native, text-based source format of the FontForge font editor. It stores a font's glyph outlines, metrics, kerning, OpenType tables and editing state, so a font can be reopened and edited losslessly and then exported to TrueType, OpenType, WOFF or Type 1.
