The plugin converts images (JPG/PNG) into **WebP in real time** before they are processed by the server. This prevents endless loading times and stops multi-megabyte photos from clogging up your storage and bandwidth.

**What you can do from the Control Panel:**

✅ **Enable/Disable** the conversion with a single click.
 ✅ **Choose whether to keep or replace** the original file (for files saved to the Media Library, you can decide to delete the JPG and keep only the optimized WebP).
 ✅ **Set the quality** of the WebP conversion.
 ✅ **Define the maximum width** of the image (automatic resizing).

**Key Features:**

- 📧 **Mail & Media:** It works both for images sent as email attachments and for those saved directly to the WordPress Media Library.
- 🔄 **Visual Loader:** When a user uploads one or more images, a loader is displayed to explain that the conversion is in progress.
- 🖼 **Single and Multiple Files:** It seamlessly handles multiple concurrent uploads.

 

⚠️ **Technical note:** It works exclusively with the standard **“File Upload”** field. It is currently NOT compatible with the “Drag & Drop” addon.

The plugin uses system libraries (**ImageMagick / GD Library**) to ensure speed and maximum quality.

If you want to try it out (perhaps in a staging environment) and help me test its stability, leave a comment or send me a private message! 📩
