jPDFOptimizer is a Java library to optimize and reduce the size of PDF documents.

jPDFOptimizer can remove unnecessary objects in PDF documents, detect and merge duplicate images and fonts, and modify image resolution, compression and color spaces to reduce size. The library provides a powerful, yet simple API to let the calling application fine tune how to optimize documents.

jPDFOptimizer is built on Qoppa Software’s extensive PDF technology and requires no third party software or drivers. The library is 100% Java and can run on any operating system for which there is a standard Java implementation, such as Windows, Linux, Unix, Solaris and others.
