Only WebP Uploads automatically converts your image uploads (JPG, PNG, GIF) to WebP format. It handles all image sizes generated by WordPress, ensuring your site serves optimized, modern image formats.
Features: 
* Automatic Conversion: Converts images immediately upon upload. 
* Space Saving: Replaces original files with lighter WebP versions. 
* Database Integration: Updates WordPress metadata so the Media Library recognizes the file as WebP. 
* Bulk Conversion: Includes a tool to scan and convert existing images in your library. 
* WP-CLI Support: Manage conversions via command line using <code>wp onlywebp</code>. 
* Smart Filename Sanitization: Automatically cleans filenames (e.g., <code>mañana.jpg</code> -> <code>manana.webp</code>). For non-Latin names (e.g., Japanese), it generates a secure unique ID to ensure compatibility. 
* Security: Checks for Imagick support and sanitizes filenames.
