Additional Features and Benefits
And there’s more to WebberZone Image Optimizer…
Originals untouched
Optimized copies are written alongside your originals. Nothing is overwritten, and deactivating the plugin serves the originals again immediately.
Quality control
Per-format quality, encoder effort and lossless mode for PNG sources. A copy that is not smaller than its source is discarded.
Privacy friendly
Everything runs on your own server. No tracking, no external requests, and no data collection.
Media library insight
See the savings for every image, and optimize or remove copies from the Media library.
Multisite compatible
Per-site queues and settings, with tables created automatically for new sites.
Developer friendly
WP-CLI commands and filters throughout let developers script conversion and customize behavior.
