About Fan Coil
Fan Coil solves a specific problem that comes up daily for anyone dealing with this task: doing it once, fast, without an account. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
