FH11 files are vector image files that are created by FreeHand 11, a discontinued product from Adobe. Because these images are made from vector graphics, the image can be scaled infinitely without losing quality in the image and are thus used to create company logos, brochures, and other media which may be ballooned in size during print.

Despite the discontinuation of the program which creates FH11 files, other Adobe programs may still load them.
