Files with the .FH11 extension contain vector image data, i.e. points, lines, and curves, as well as gradients and colors, which can be scaled without any loss of quality.

FH11 files are created using the FreeHand 11 drawing software for creating brochures, logos, and other printing materials. The FreeHand 11 software was developed by Macromedia and later acquired by Adobe Systems. In 2007, Adobe stopped developing this project.
