Mass Resizer allows bulk image resizing, safe WebP conversion, and automatic metadata preservation — improving page speed and optimizing media libraries at scale.

== Description ==

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.

###  Key Features

**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.

== Frequently Asked Questions ==

= Does the plugin delete my original images? =  
Only when both features are enabled:  
• “Replace old images”  
• “Delete original images”  
Otherwise, deletion is blocked to prevent broken pages.

= Will my SEO metadata be preserved? =  
Yes. WebP attachments automatically inherit:  
• alt text  
• caption  
• description  
• parent relation  
• date fields  

= Does Mass Resizer modify existing posts? =  
If “Replace old images” is enabled, the plugin updates posts/pages that contain the converted images.  
Otherwise, no post content is changed.

= Can I use it on a large site? =  
Yes. The plugin is optimized to handle large numbers of images, and includes safety checks, capability detection, and detailed logging.
