Xmorph loads, saves, warps, and dissolves images, and loads, saves, creates, and manipulates control meshes which determine the warping. The technique was invented and first used by Industrial Light and Magic, and is commonly called "morphing".

Xmorph uses the Targa image format exclusively. Other software is needed to convert to other image formats or to movies. (Due to a bug, Xmorph's images are unreadable by John Bradley's XV.)

xmorph is a GUI for libmorph, using the X Toolkit; the package also contains a text-only program called morph.
