Does DashO™ compress class files ?
No. We leave compression to jar or zip. DashO™ actually reduces the size of your class files by a combination of renaming, removal of unneeded information, and other space saving optimizations that always maintain compatibility with Java™’s class file format. For example, DashO™ Pro removes unneeded elements from a program. It removes unused methods (public, private, etc.) and unused fields. It also removes unused constant pool entries and other unneeded class file attributes.
