Bitmap Font Generator

3 min Art & Sprites

Generate a styled 36-glyph sheet (A–Z and 0–9) from a prompt and pack it into a bitmap-font atlas with a JSON glyph map in your browser — drop-in pixel fonts for your UI. Powered by AnnoMotion AI.

Before you start
A description of the letterforms — "chunky bevelled arcade lettering".
What you end up with
A glyph sheet PNG, a packed atlas PNG, and a JSON glyph map.

Step by step

  1. Describe the font

    Describe the letters themselves — weight, edges, material — not the game they are for.

  2. Pick a style, then build the atlas

    Generate the sheet, then press Build atlas. The packing runs in your browser and produces the atlas and the coordinate map together.

Worth knowing

  • You get A–Z and 0–9 — thirty-six glyphs, no punctuation. Plan for that.
  • The sheet always comes back in A–Z then 0–9 order on a 6 × 6 grid, so the Build atlas defaults already match it — no grid to tune.
  • The map is JSON with the position and size of each character, not a BMFont .fnt file. Most engines will take it with a few lines of loader code.
