Convert TrueType font to Bitmap format online
TrueType format is an outline font standard developed by Apple in the late 1980s. It became popular among font developers because it provided them with a high degree of control over how their fonts are displayed, right down to particular pixels, at various font sizes. ( wikipedia )
Bitmap format stores each glyph as an array of pixels (that is, a bitmap). It is less commonly known as a raster font or a pixel font. Bitmap fonts are simply collections of raster images of glyphs. ( wikipedia )
