NinjaWeb

NinjaWeb Smart Media Optimizer is a local media optimization engine for WordPress site owners, maintainers, and agencies who want controlled image processing without relying on an external optimization service.
The plugin runs inside WordPress using the image tools available on your server. There are no API keys, no credits, no monthly image caps, no required CDN, and no subscription gate for the core workflow. You control when images are scanned, queued, optimized, retried, and restored.
The workflow is designed for transparency. Instead of hiding the process behind a remote service, the plugin provides a real-time Media Engine panel with progress, current job details, live activity logging, pause/resume/stop controls, failed-item retry, and clear restore options when backups are available.

<li>Backup originals before changes</li>
<li>Restore selected images or restore all originals when backups exist</li>

<li>Preserves attachment IDs instead of replacing posts or breaking relationships</li>
<li>Global dashboard stats for total images, optimized images, pending images, backups, and optimized media size saved</li>
</ul>
NinjaWeb Smart Media Optimizer is intentionally built for a deliberate, auditable workflow rather than remote black-box processing.
