jPDFImages is a Java™ library to export images from PDF files and to import images into PDF files. jPDFImages can create images from pages in a PDF document and export them as JPEG, TIFF or PNG images. Additionally, it can return the image of any page in the document to the host Java application as a BufferedImage for further processing or to save in different formats.

jPDFImages can also create documents or add pages to existing documents by importing TIFF, JPEG and PNG images. After creating or modifying a document, the library can save to the local file system or to an output stream to be able to serve the document directly to a client browser when working within a J2EE server.

jPDFImages is built on top of Qoppa's proprietary PDF technology so you do not have to install any third party software or drivers. jPDFImages is also 100% Java, so it is completely platform independent and can run on Windows, Linux, Unix, Mac OSX and any other platform that supports the Java runtime environment.
