Library / package	License	Description
	Freeware	Read Microsoft Windows ICO files. Supports the javax.imageio framework, but the library can also be used from older (pre 1.4) Java runtime environments.
	Special license on the website.	Read PPM (Portable PixMap), write GIF and PPM.
	Commercial	Various raster image file formats, including TIFF.
	Apache Software License 1.1	The Batik toolkit also contains image I/O packages below the org.apache.batik.ext.awt.image.codec hierarchy. Read and write PNG and TIFF.
	Free for personal use.	Read BMP files with 1, 8 or 24 bits, write BMP files with 24 bits. A demo viewer and documentation are included.
	Unknown to me.	Read Windows BMP files. This one comes with a nice introduction one how to deal with images in Java.
	None specified.	BMP loader, includes sample application.
	None specified.	Javaworld.com tip 60. Write Windows BMP files.
	Commercial	Supports MO:DCA (IOCA [CCITT G3,G4, G4-MMR & JPEG encoding] and PTOCA), AFP (LIST3820), TIFF (various compression types), ASCII, EBCDIC, BMP, GIF, JPEG.
	Commercial, evaluation version available.	Read and write DICOM image files. Uses the ImageIO API which has been introduced with Java 1.4.
	Commercial	Supports TIFF Group 4 decoding. Seems to be tested with all kinds of browsers on different platforms to be used in an applet.
	Freeware	Read and write one image and animated GIF. Includes a high quality color quantizer (a port of to Java) to reduce truecolor to palette images. A class to read uncompressed and RLE-compressed PSD files (Photoshop) was recently added.
	Free	Read RLE GIF files. RLE (runlength encoding) will result in larger files compared to standard LZW GIFs, but has not the patent problems of LZW. The corresponding encoder was never completed, and the author does not intend to do so in the future.
	?	A GIF encoder, plus an implementation of an to reduce the number of colors, as GIF only supports up to 256 different colors in an image.
	Commercial (PRO and LIGHT versions)	Read and write GIF files. Supports creation of animations including color image quantization, text rendering etc. Offers several image editing algorithms, adding comments and watermarking GIFs (watermarking here means adding images on top of other images, not adding information to identify stolen images).
	Public Domain	Based on the ACME encoder, this package offers more features, including encoding of animated GIFs and textual comments. Source code included.
	Apache License	Write one-image and animated GIF files. Supports transpareny. Comes with source code.
	Free for non-commercial use.	Write GIF files.
	IBM Internet License Agreement	See the Image Conversion section, it has code to read and write Windows BMP files.
	Commercial	Supports reading and writing of JPEG, PNG, BMP, GIF and PCX as well as dithering (presumably in combination with color quantization).
	LGPL	Read Windows icon files (.ico). To be used as part of the ImageIO framework, requires Java 1.4+.
	LGPL	Write PNG, PICT, BMP, TIFF, TGA. Reads some of those as well. Class library and Java Beans. Seems to come with its own JPEG encoder, independent of IJG code.
	Free for non-commercial use.	Read and write GIF, TIFF, JPEG. Read BMP, DICOM, FITS and PGM.
ImageGear	Commercial	Read and write various formats, including TIFF, BMP, MO:DCA, IOCA and CALS.
ImageroReader	Free for non-commercial use.	Read BMP, TGA, TIFF, PNG, JNG, MNG, JPEG, CRW, PSD, GIF and MRW. Read thumbnails and metadata from those formats. Read thumbnails from THM. Read all embedded images from EPS files.
	Freeware	[Page is gone; I'm trying to find the author] Saves an Image instance as a GIF file. No source code is provided.
ImageToolz	?	Read and write PPM and Windows BMP files. Also can load GIF and JPG via Toolkit. Uses the Obrador codec to write JPEGs. Comes with source code.
	Sun license.	An image processing toolkit; Sun also provides the source code for the 1.0 image codecs. There is a page dedicated to image I/O issues.
	Sun license.	Reader-writer plug-ins for the 1.4+ javax.imageio package. Supported: BMP, JPEG, JPEG 2000, PNG, PNM, Raw, TIFF, and WBMP image formats.
Java Image Loader	LGPL	Image reading that is fast (using native code via JNI) and uses relatively little memory for GIF, JPEG, PNG (1.0), TIFF, TGA, BMP and XPM/XBM. Seems to work under Win32 only at the moment, but uses free, well-tested standard libraries like , , etc. which work under many platforms and are relatively easy to port to new ones.
	LGPL	Read PNG (Portable Network Graphics) files.
JDDK (Java DICOM Development Kit)	Commercial library, 30 day trial version.	Read and write DICOM, the file format for medial images.
	Sun Binary Code License Agreement	Sun development kit to read and write several formats, including GIF, JPEG, TIFF, PNG, PICT, PSD, BMP, TGA, ICO, CUR, RAS, XBM, XPM and PCX.
JIU—Java Imaging Utilities	GPL	Java imaging library with support for PNG, GIF, IFF, RAS, PCD, PBM/PGM/PPM/PNM, PSD, TIFF (uncompressed, PackBits, Deflate, CCITT-1D, LogLuv).
	?	An implementation of the image compression standard.
	LGPL	A wrapper to the functionality of ImageMagick, a powerful free imaging library (supported formats). JNI is used to access native code (written in C).
	Special license at the beginning of each source code file.	Read and write JPEG files.
	Commercial (previously freeware)	Write JPEG files.
jrawio	MIT License	Read various RAW formats of digital cameras like Nikon's NEF or CRW/CR2 with Canon. Pure Java code.
	(L)GPL	Read TIFF (Tagged Image File Format) files. Some files of the toolkit seem to be under the GPL, others under the LGPL.
	LGPL	Read and write DICOM, ECAT, GE, MINC, AFNI, ANALYZE, and NIFTI (medical image file formats).
	Commercial	Read and write LuraTech's proprietary LWF format. Offers several types of compression, lossy and lossless, some of the wavelet-based. Java 1.1.7 or higher required. Trial version and applets available.

	LGPL	Read and write PNG (Portable Network Graphics) files.
Sun's com.sun.image.codec.jpeg package	Unknown to me (maybe same as Java).	Read and write JPEG files; classes included in Sun's /JRE 1.2+, but not standard library classes, so you cannot rely on them being there with every Java VM! Documentation can be downloaded from Sun's website.
	Commercial, trial version available	Read TIFF, BMP, GIF, JPG and PNG. Various TIFF compression types are supported, decoding is relatively fast. Also includes printing, viewing and image processing functionality. Available as or .
