What Optimus is
Optimus is a WordPress image-compression plugin that automatically processes uploaded JPEG and PNG files. It targets lossless PNG compression and slight lossy JPEG compression while maintaining visible appearance, and it optimizes originals, previews, and thumbnails. Metadata is removed by default, with an option to retain EXIF and IPTC information. The plugin supports batch processing, progressive JPEG creation, WordPress Multisite, WooCommerce, and a Bulk Optimizer for existing images. Paid HQ plans add WebP conversion. Images are sent to Optimus servers, which the service says delete each file immediately after compression; servers are stated to be in Germany and connections use SSL. The free plan allows 100 KB files. HQ plans allow 10 MB and unlimited images. HQ licenses cover own projects, while HQ PRO covers customer projects.
