Beschrijving
WordPress automatically creates multiple copies of every image you upload in different sizes (thumbnail, medium, large, and more). Over time, this wastes a significant amount of disk space, especially on large sites with thousands of images.
Imadero scans your media library, finds all auto-generated thumbnails, and removes them safely. It also updates all references in your posts, pages, and metadata to use the original image instead.
Features
- Scan your media library to find all auto-generated thumbnails
- Preview how many files and how much disk space can be freed before deleting anything
- Delete all thumbnails in batches (safe for large sites)
- Rewrite all database references (posts, meta, options) to use the original image
- Prevent WordPress from generating thumbnails on future uploads
- Handles serialized data safely (works with Elementor, Divi, WPBakery, and other page builders)
- Handles Gutenberg block attributes (sizeSlug, CSS classes)
- Removes WordPress -scaled images and restores the original
- Batch processing prevents timeouts on large installations
- Works with WooCommerce product images
How It Works
- Go to Tools > Imadero in your WordPress admin
- Click Start Scan to find all auto-generated thumbnails
- Review the results: number of thumbnails and disk space used
- Click Delete Thumbnails to remove them and update database references
- Optionally enable Disable automatic thumbnail generation to prevent future thumbnails
Important Notes
- Always create a backup before running the cleanup
- The deletion process cannot be undone
- WordPress will automatically fall back to the original image where thumbnails were used
- The plugin works per site on Multisite installations
Installatie

FAQ
-
Will my images break after removing thumbnails?
-
No. WordPress automatically falls back to the original image when a requested size is not available. Your images will still display correctly.
-
Does this work with page builders like Elementor or Divi?
-
Yes. Imadero safely handles serialized data in the database, which is how most page builders store their content.
-
Can I undo the deletion?
-
No. The thumbnail files are permanently deleted. We strongly recommend creating a backup before running the cleanup.
-
Does this affect the original uploaded images?
-
No. Only the auto-generated copies (thumbnails) are removed. Your original images are never touched.
-
What happens with future uploads?
-
By default, WordPress will continue to generate thumbnails for new uploads. You can disable this by enabling the Disable automatic thumbnail generation option in the plugin settings.
-
Does this work on Multisite?
-
Yes. The plugin works on a per-site basis. Each site administrator can run the cleanup independently.
