Callisto

Callisto is a focused bitmap font generator for turning TTF and OTF fonts into ready-to-use bitmap font atlases. Select your characters, preview the result, and export raster, SDF, MSDF, or MTSDF fonts with BMFont-compatible descriptors in PNG, TGA, and other formats.

Designed for game developers, Callisto makes it easy to control font size, padding, spacing, colors, kerning, texture dimensions, and export settings from one clean workspace.
