| Pros | WebP conversion and bulk optimisation in the free version; Local server tools or cloud API optimisation; Works with NextGEN Gallery and Flagallery libraries | 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 |
| Cons | Higher optimisation levels need a paid API key; Some CDN and cloud features call the vendor's servers | 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 |
