Birdfont
A cross-platform font editor with Bézier outlines, background images, kerning, and TTF, OTF, and SVG font export.
Why use it
Birdfont works well for title lettering, icon fonts, and small pixel-font sets that extend a game's visual identity into UI.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
The GPL application is free, while donations and subscriptions shown by the project support development rather than unlock commercial use; large character sets, complex OpenType shaping, and professional hinting still require substantial work.
