Welcome

We are the world's leading provider of optimization and obfuscation software for Java and for Android. We develop and support ProGuard, our successful open source obfuscator for Java, and DexGuard, its specialized sibling for Android. Our goal is to optimize and protect your applications, to save you time, effort, and money.

DexGuard

DexGuard is our specialized optimizer and obfuscator for Android. Create apps that are faster, more compact, and more difficult to crack. DexGuard has you covered, automatically applying the recommended application protection techniques for Android, and more.

Professional ProGuard Support

ProGuard is free, but setting up optimization and obfuscation may require some time and effort. If you'd like a professional support contract, we'll be happy to help. As the developers of ProGuard, we have years of experience from thousands of interactions with ProGuard users. We are confident about our software and about our expertise.

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.
