| Pros | Resizes uploads automatically, with no action from the contributor; Separate size limits for Media Library and other uploads; Bulk resize and per-image resize from the Media Library | Bulk and on-upload image compression at no cost; Lazy loading for images and embedded video; Works with common page builders, WooCommerce and caching plugins |
| Cons | Replaces the original, so the full-size file cannot be recovered; Uses the standard WordPress resize, so output is not heavily optimised; No paid edition; support is through the WordPress.org forum | WebP, AVIF, resizing and the image CDN need Smush Pro; Images are sent to the WPMU DEV API for compression |
