## Descrizione

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`
wp onlywebp`. * **Smart Filename Sanitization:** Automatically cleans filenames (
e.g., `mañana.jpg` -> `manana.webp`). For non-Latin names (e.g., Japanese), it generates
a secure unique ID to ensure compatibility. * **Security:** Checks for Imagick support
and sanitizes filenames.
