jWordConvert is a Java library that can read and render Word documents natively, converting them to PDF or images, or printing them. The library does not use any third party software or native calls and can be run in a server environment, integrated into a desktop application, or embedded in a Web page as a Java applet. It supports permissions and passwords for PDF documents, and conversion to JPEG, TIFF, or PNG.
