I built a free bitmap font generator that converts any reference image into Unity/Godot-ready font sheets
Hey IH! I'm a Spine animator at a game studio — not a developer — and I just launched a small web tool that solves a real workflow pain.
Our designer kept generating beautiful font styles with AI image tools, but none of the outputs could be directly imported into Unity or Godot. Game engines need a proper BMFont sheet (.png + .fnt file) to use bitmap fonts — and converting AI output into that format was a huge manual headache.
So I built CopyPxl to bridge that gap:
Upload any reference image → get a complete bitmap font sheet in BMFont format, ready to import into your game engine.
What it outputs:
- font.png (sprite sheet with all characters A-Z, 0-9, symbols)
- font.fnt (BMFont descriptor file)
- ZIP download
Works with: Unity (TextMeshPro + Legacy GUI), Godot, Phaser, LibGDX

For context on how I built this: I'm not a web dev. I started with a messy Python script, then slowly turned it into a full web app with a lot of iteration (and Claude's help for the coding parts). The whole journey from "frustrated at work" to "live SaaS product" took about a month.
Happy to answer any questions — especially from game devs who've dealt with custom font pipelines!
