How to convert TTF to FNT with Fontforge

I recommend trying Hiero. It can convert any installed system font or font file into .fnt.

You can download it from BadLogicGames.

  • Open runnable-hiero.jar
  • Select the font you want to convert.
    • For installed fonts on your PC: Select System
    • For downloaded font files: Select File and choose a font by clicking ...
  • In the menubar, select File → Save BMFont files (text)
  • Choose a save location and filename ending in .fnt

If done correctly, you should have two files for font_name.fnt and font_name.png

Hiero v3.1 - Bitmap Font Tool


FNT is a bitmap format while TTF is an outline/vector format. To get FNT output, you'll first need to create a bitmap strike or strikes. Fontforge can do this if it has been built with Freetype included:

  • Go to Element -> Bitmap Strikes Available.
  • Select the 'Win' button
  • Under 'Point Sizes' enter the size (or sizes) you want.
  • Tick 'Use FreeType' and 'Create Rasterized Strikes' Click OK.

You should now have a bitmap strike to work with. Go to Generate Fonts; on the left side select 'No Outline Font', and on the right side select Windows FNT, pick the size you want, and generate.
