It supports gradients, multi-layer effects, and direct game engine integration. You can go from font file to exported bitmap in minutes.

What is a Bitmap Font?

A bitmap font stores each character (glyph) as a pre-rendered image in a texture atlas. The result is pixel-perfect rendering at a fixed size, which works well for games, embedded systems, and UIs where rendering speed and visual consistency matter.

How to Create Bitmap Fonts - Step by Step Guide
