Description
Milyutin Image Optimizer is a fast, lightweight, and completely local image optimization plugin for WordPress. It automatically converts your uploaded JPG and PNG images into the modern WebP format, significantly reducing file sizes without losing visual quality.
Unlike other services, this plugin does not use external APIs or cloud servers. All optimization happens directly on your server, ensuring maximum privacy and zero subscription fees.
Key Features:
- Automatic WebP Conversion: Converts new JPG/PNG uploads to WebP on the fly.
- Thumbnail Optimization: Automatically generates WebP versions for all your theme’s thumbnail sizes.
- Bulk Optimization: Convert your entire existing media library in batches directly from the dashboard.
- Activity Logs: See exactly which files were optimized, how much space was saved, and catch any errors.
- Statistics Dashboard: Track total disk space saved by the plugin.
- Lightweight & Fast: Built with clean code, no jQuery dependencies on the frontend, and no external requests.

FAQ
-
Does this plugin modify my original images?
-
In the Lite version, no. The plugin creates new
.webpfiles next to your originals. Your original JPG and PNG files remain completely untouched and intact. (The Pro version includes an option to delete originals to save space). -
What if my server doesn’t support WebP?
-
The plugin checks your server’s capabilities (via GD or Imagick). If WebP is not supported, a clear warning will be displayed in the admin panel, and the plugin will safely skip conversion.
-
Do I need an API key or cloud account?
-
No. All optimization is done locally on your own hosting server. There are no limits, no monthly fees, and your images never leave your server.
-
Can I convert images that were uploaded before installing the plugin?
-
Yes! Go to the plugin settings page and use the “Bulk Conversion” tool to process your existing media library.
