🚀 How It Works:
When you upload an image, WordPress automatically generates multiple sizes (thumbnail, medium, large, etc.). This plugin hooks into the image generation process and removes any sizes you’ve disabled from the generation list. This means:
- ✅ New images won’t generate the disabled sizes
- ✅ Existing images remain untouched
- ✅ Storage space is saved on future uploads
- ✅ Performance improves with fewer image files
- ✅ Immediate effect after saving settings
🎨 User Experience Features:
- Statistics Dashboard: See total, disabled, and active image sizes at a glance
- Visual Cards: Each image size displayed in an attractive card with status indicators
- Smart Labels: Clear distinction between default and custom image sizes
- Dimension Display: Shows actual pixel dimensions for each size
- Status Indicators: Color-coded enabled/disabled states
- Bulk Actions: Efficiently manage multiple sizes at once
- Success Messages: Clear feedback for all operations
- Helpful Tips: Built-in guidance for optimal usage
💡 Perfect For:
- Developers who want to control which image sizes are generated

FAQ
-
Does this plugin delete existing images?
-
No, absolutely not! This plugin only prevents new unused image sizes from being generated. It does not delete any existing images or image sizes that are already on your server. Your current media library remains completely untouched.
-
Will this affect my current theme or plugins?
-
No, this plugin only affects the generation of new image sizes. Your theme and plugins will continue to work normally with existing images. The plugin only prevents new sizes from being created during future uploads.
-
Can I re-enable a size after disabling it?
-
Yes, absolutely! Simply go to Settings Image Sizes, uncheck the box for the size you want to re-enable, and save your changes. The size will immediately be available for new image uploads.
-
What happens if I disable all image sizes?
-
This is not recommended. If you disable all image sizes, only the original uploaded image will be stored. This may break your theme’s layout and functionality. We recommend keeping at least the thumbnail and medium sizes enabled.
-
Does this work with custom image sizes added by themes or plugins?
-
Yes! The plugin automatically detects all registered image sizes including custom ones added by themes and plugins. You’ll see them clearly labeled as «Custom» in the admin interface.
-
Is this plugin compatible with my hosting provider?
-
Yes, this plugin works with any hosting provider that supports WordPress. It only uses standard WordPress functions and doesn’t require any special server configurations or additional software.
-
Will this improve my site’s performance?
-
Yes! By reducing the number of image files generated, you’ll save storage space and potentially improve page load times, especially for image-heavy pages. Fewer files mean faster loading and better user experience.
-
How do I know which sizes to disable?
-
Start with custom sizes added by themes or plugins that you don’t actively use. Keep default sizes (thumbnail, medium, large) enabled unless you’re certain you don’t need them. The plugin clearly labels which sizes are default vs. custom to help you make informed decisions.
-
Can I use keyboard shortcuts?
-
Yes! The plugin includes several keyboard shortcuts for efficient management:
– Ctrl+A (or Cmd+A on Mac): Select all image sizes
– Ctrl+D (or Cmd+D on Mac): Deselect all image sizes
– Escape: Clear all selections
– Enter/Space: Toggle individual size selection -
Is this plugin accessible?
-
Yes! The plugin is built with accessibility in mind, including:
– Full keyboard navigation support
