The Java Image I/O API (the javax.imageio package) contains the basic classes and interfaces for reading/writing BufferedImages and RenderedImages from/to image files and streams.

Many common image I/O operations may be performed using the static methods of the ImageIO class.

The package contains classes describing the contents of image files, including metadata and thumbnails (IIOImage); for controlling the image reading process (ImageReader, ImageReadParam, and ImageTypeSpecifier) and image writing process (ImageWriter and ImageWriteParam); for performing transcoding between formats (ImageTranscoder), and for reporting errors (IIOException).

All implementations of javax.imageio provide the following standard image format plug-ins: JPEG, PNG, BMP, WBMP and GIF.

The javax.imageio package has been available since Java (J2SE) 1.4.
