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.

Mass Resizer is a lightweight but powerful plugin for bulk image optimization. 
It resizes large images, converts them to WebP, replaces them across posts/pages, and safely manages media files without risking broken content.
<h3>Key Features</h3>
Bulk Image Resize 
• Automatically resizes images to a maximum width/height 
• Maintains aspect ratio (no cropping, unless enabled) 
• Skips small images to reduce unnecessary processing
Safe WebP Conversion 
• Converts JPEG/PNG to modern WebP format 
• Inherits original image metadata (alt, caption, description) 
• Creates proper attachment entries with parent relations 
• Preserves titles and SEO attributes
Safe Replace Mode 
• Replaces all occurrences of images in posts and pages 
• Updates featured images as well 
• Multiple registered sizes are replaced (full + intermediate sizes)
Safe Delete Mode 
To prevent content breakage, original images are deleted only when both conditions are met: 
1. Replace Old Images = enabled 
2. Crop = disabled 
If delete was requested in unsafe configuration, the plugin logs a warning and ignores the deletion.
Admin Statistics + Logs 
After each run, the plugin displays a detailed summary: 
• Images cropped 
• Images converted to WebP 
• Pages updated 
• Originals deleted 
• Total completed operations
All warnings (missing files, unsupported types, editor errors) are logged and shown to the administrator.
Automatic Server Capability Detection 
The plugin checks whether your server supports: 
• JPEG editing 
• WebP conversion
Unsupported features are automatically disabled with an explanation.
Fully Internationalized (i18n) 
All dynamic strings include translator comments, following WordPress.org standards.
