ProGuard is a Java class file shrinker and obfuscator. It detects and removes unused classes, fields, methods, and attributes, then renames the remaining classes, fields, and methods using short, meaningless names. The resulting jars are smaller and harder to reverse-engineer. Advantages of ProGuard compared to other Java shrinkers and obfuscators are compact template-based configuration, memory efficiency, and speed.
