Img Optimizer Gradle Plugin is a build-time utility for Android projects that automatically compresses PNG images to reduce APK size. It supports both lossless compression (no quality loss) and near-lossless or more aggressive compression modes, depending on configuration. The plugin runs during the Gradle build cycle, scanning image assets and applying optimizations transparently, which helps minimize the app’s binary footprint without manual image editing. Because it is integrated into the build, it can process only changed images and skip redundant work, improving performance. Its configuration is minimal, making it easy to adopt in existing Android projects. For apps sensitive to download size or memory usage, this plugin offers a practical way to squeeze out extra gains in deployment efficiency.
