An Open Source Java class file optimizer, shrinker, preverifier, and obfuscator tool for Linux, Windows and Mac
The ProGuard project is capable of detecting and removing unused Java classes, attributes, methods, and fields. It can also be used to effortlessly optimize bytecode, as well as to remove unused instructions.
In addition, the ProGuard software can rename the remaining Java classes, methods and fields using short meaningless names, generating jar files that are smaller, as well as harder to reverse-engineer.
Being written in Java, ProGuard is a cross-platform application that runs well on any platform where the Java runtime environment is installed, including Linux, Microsoft Windows and Mac OS X. It is integrated in Google's Android SDK, Intel's TXE SDK, and in Oracle's Wireless Toolkit.
