UFO (Unified Font Object)

UFO, or Unified Font Object, is a file format used by font designers to create and modify digital fonts. It organizes all the necessary data—such as shapes of letters, spacing, and kerning—into a single, structured folder. This format is flexible and human-readable, making it easier for designers to edit fonts during development. Once finalized, a UFO can be exported into common font formats like OTF or TTF for use in digital typography. Essentially, UFO acts as a consistent, organized container for font design information, streamlining the creation process and supporting collaboration.
