ProGuard

The open source optimizer for Java bytecode

ProGuard is the most popular optimizer for Java bytecode. It makes your Java and Android applications up to 90% smaller and up to 20% faster. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods.

ProGuard can be used free of charge to process your applications, commercial or not. The ProGuard code itself is copyrighted and is distributed under the terms of the GNU General Public License (GPL), version 2. The user manual is copyrighted as well and may only be redistributed in its original form along with the unmodified code.
