FT12 is a legacy vector graphics template format originally developed by Macromedia and later maintained by Adobe Systems for the FreeHand application. It functions as a blueprint containing pre-defined layouts, styles, and vector paths used to standardize the creation of illustrations and print designs. Since Adobe discontinued FreeHand development in 2007, this format is considered obsolete and typically requires specific conversion software or older application versions to view.
