Recently one of our readers asked us how they can bulk remove featured images from posts in WordPress? At WPBeginner, we have discussed featured images (post thumbnails) many times. We showed you how to add featured images in WordPress, how to add new image sizes in WordPress, how to regenerate thumbnails, we even showed you how to add multiple featured images to a post in WordPress. In this article we will show you how to bulk remove featured images from posts in WordPress.
The Problem With Bulk Removal of Post Thumbnails or Featured Images
Unfortunately, by default you can only remove featured images by editing each post and removing the featured image. Now if a user has hundreds of posts with featured images, then removing them one by one can be a very time consuming task. Instead, we are going to try a different approach. We will run a database query and unset the featured images on all posts.
Before you proceed, please note that the code below will remove featured images from all posts on your WordPress site by simply just pasting. Also note that this code will not delete any of your uploaded images, they will still be available in Media Library and you can reuse them anytime.
All you need to do is copy and paste this code in your theme’s functions.php file.
global $wpdb;
$wpdb->query( "
DELETE FROM $wpdb->postmeta
WHERE meta_key = '_thumbnail_id'
" );
That’s all. As soon as you save your functions.php file this script will run a database query and remove featured images from all posts.
Important: Please remove this code immediately after saving your functions.php file. You will not be able to set featured images in WordPress as this code will keep removing featured images from posts.
We hope this article helped you save some time and allowed you to bulk remove featured images from WordPress posts. For questions and feedback please leave a comment below.

Thank you.
Deleting all the server images assigned to the thumbnails is relatively simple, now, how to condition to delete all uploads not used by the server as featured images? This should be the most interesting, clean the images not used by the system, in order to polish the machine resources deleting junk images, not used.
Yes! So helpful, thank you!!!
it works thank you , but what if i want to remove the post that don’t have feature image , how can i do that ?
Thanks a lot, you really rocks guys!!!
it works ! just don’t use with child theme.
Followed the instructions to the letter. Got this error message: Parse error: syntax error, unexpected ‘$wpdb’ (T_VARIABLE) in /home/ruznnjep/public_html/wp-content/themes/natalie/functions.php on line 411
Blog broken. Had to reinstall. Thanks.
Thank you! It is an excellent advice to remove all featured images
Is there anyway to undo this? I didnt realise it would remove thumbnail images as well. I have tried restoring the thumbnails but it is not working. Thanks
#1. Are we 100% positive that the current code does NOT delete any images from my media folder? And simply “unset” them from featured image?
#2. You mention “However, the query can be modify to exclude certain post types.” Can you share the code I would use to avoid a category with ID=25?
Thank you so much,
Mike

After delete my related images my images from homepage desappeared, but when I go to post details it appears normally. Before run the script, the homepage used the images from inside the post and not from related images, so I really don’t know why they desappeared from my homepage. Do you have any idea why this happened?
Thanks a lot, you helped me saved a lot of time.
Is there a plugin or codes to remove both post and images attached to a post when we delete it? I mean if i delete a post i also want to delete images related to that post also.
You will have to delete images from media library.
Wish someone would have made a plugin like that because deleting images from 100-200 posts is very time consuming… ?? if any plugin of that kind comes up pls do update it in ur site.. thanks for your reply
Is it possible to query a specific category and remove just those categories posts featured images?
Thanks man!!
BEWARE
I used this code yesterday to try to delete the featured images as part of an upgrade to a new WordPress theme. While it did delete the featured images from posts, it also deleted them from the media library and I think it’s also deleted the original files from the server.
Having used this code to try and speed thing up, I now find myself having to re-install and re-link over 2,500 images for my site.
Justin, we tested the code again. It does not delete files from your media library or your server. It just unsets featured images.
I am facing the same problem. After adding this code, few images are being erased from media library.
Sudip, thank you for notifying us. We have updated the article. Please try the new code instead.
One should also note that this deletes featured images not just from standard post, but from all posts (including custom post types), correct?
Yes this is correct. However, the query can be modify to exclude certain post types.
Wouldn’t it be easier to just run a query on DB directly?
Yep, and this is exactly what this code is doing.
