Var2Stat

Convert variable fonts to static font instances with configuration-based axis control.

Features

• Extract axis information and generate optimized configuration files
• Smart axis inheritance (global defaults with variant overrides)
• True static output with all variation tables removed

Installation

uv tool install var2stat

Usage

• Step 1: Generate config from variable font (creates <font_file>-config.json in the same directory as the font):

  uvx var2stat config <font_file.ttf>

• Step 2: Generate static fonts from a config file:

  uvx var2stat generate <config_file.json>

  Output is always saved to a folder named after the canonicalized font name, with files named <canonical_font_name>_<variant>.ttf.

Config Structure

{
  "$schema": "https://raw.githubusercontent.com/decipher3114/Var2Stat/refs/heads/main/schema.json",
  "file": "font.ttf",
  "font_name": "Font Name",

  "variants": {
    "Regular": { "wght": 400 },
    "Bold": { "wght": 700 }
  }
}

• Global axes with null use font defaults
• Variant axes override global values
