ProGuard: Open Source Optimizer for Java and Kotlin. ProGuard is the most popular optimizer for Java bytecode. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods. ProGuard reduces the download and startup time of Android applications and improves their performance on mobile devices. ProGuard obfuscates Java applications and pre-verifies the processed code for Java Micro Edition and for Java 6 and higher. ProGuard optimizes and obfuscates Java applications for cell phones, Blu-ray players, set-top boxes and other constrained devices. ProGuard fully supports Java and Kotlin applications, enabling developers to take full advantage of these languages’ features without sacrificing performance or security. ProGuard is a command-line tool with an optional graphical user interface. ProGuard is fast: It processes small Android applications and entire runtime libraries in seconds.
