Use ProGuard®, Guardsquare’s open-source shrinker for Java bytecode, to enhance and optimize your code.
The original Java optimizer for Android apps.
Use ProGuard to shrink any Java or Kotlin app, whether on mobile, embedded or on desktop.
ProGuard optimizes apps by reducing their size and improving performance, ensuring a more efficient and seamless user experience.
ProGuard is a command-line tool that reduces app size by shrinking bytecode; it obfuscates the names of classes, fields and methods. It’s an ideal fit for developers working with Java or Kotlin who are primarily interested in an Android optimizer.
Although ProGuard is a great start to mobile app optimization, its primary purpose is to shrink Java/Kotlin apps. DexGuard, our comprehensive Android mobile application security product provides protection from static and dynamic analysis through layered obfuscation and encryption techniques complemented by automated RASP checks and built-in malware defenses. DexGuard, integrates seamlessly with your existing ProGuard (or R8) configuration.
