'''Ink Serialized Format''' ('''ISF''') is a [[Microsoft]] format to store written ink information. The format is mainly used for mobile devices like [[Personal digital assistant]]s, [[tablet computer|tablet PC]]s and [[Ultra-Mobile PC]]s to store data entered with a [[Stylus (computing)|stylus]].

An ink object is simply a sequence of strokes, where each stroke is a sequence of points, and the points are X, and Y coordinates. Many of the new mobile devices can also provide information such as pressure, and angle. In addition, it can be used to store custom information along with the ink data.
