TwelveMonkeys ImageIO is a collection of plug-ins for Java's ImageIO.

These plugins extends the number of image file formats supported in Java, using the javax.imageio.* package. The main purpose of this project is to provide support for formats not covered by the JDK itself.

Support for formats is important, both to be able to read data found "in the wild", as well as to maintain access to data in legacy formats. Because there is lots of legacy data out there, we see the need for open implementations of readers for popular formats. The goal is to create a set of efficient and robust ImageIO plug-ins, that can be distributed independently.
