    <p>
        Reclaim disk space while preserving art quality. Opaque PNG art (backgrounds, covers, screenshots) is converted to high-quality JPEG, oversized images are downscaled, and metadata is stripped. Images with transparency (icons, logos) are never converted. Optimization replaces the original files in place and runs in the background.
    </p>
