ProGuard is our free generic optimizer and obfuscator for Java bytecode. Over the years, it has solidly become the industry standard in its field. It is the default tool in development environments like Oracle's Wireless Toolkit, Netbeans, EclipseME, Intel's TXE SDK, and Google's Android SDK. Technically, ProGuard detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names.
