[Support request] Reduce the number of image sizes that your WordPress has registered

[Deyson]

Hello and good day.

Recently, my host just made me aware that my installation has registered up to 17 image sizes.

So my question is how do I find out what image sizes are being actively used ( I do not want to delete the images my website needs)
, de-register the unwanted image sizes, and then the best way to delete the unused images.

Please let me know what you think. 🤔
Thank you and have an Amazing Day! 🙂

Hi there,

tricky – i don’t think theres an easy way to tell which attachment sizes are not required.
You would need to first find out what sizes are being registered and then investigate each plugin / function that has registered them to find out where they may be used.

I found this article which covers how to list the attachment sizes and how to unregister them:

https://codexin.com/remove-unused-wordpress-image-sizes/

I also found this reply to a similar topic where the user provides some plugins:

https://wordpress.org/support/topic/remove-thumbnail-size-not-used/#post-14306830

I would recommend making a backup or doing this on a staging site just to be safe

Awesome! Thank you @David! 🙂

Also, is there a way to know which images are needed by GeneratePress’s Niche.

Thank you and have a Fantastic Day! 🙂

Out of the box, Niche uses very few sizes.
I don’t recall adding any non Woocommerce images, so the sizes here:

https://woocommerce.com/document/image-sizes-theme-developers/#section-4

are probably the only ones that are used.

Awesome! That would save a lot of time.

Thank you and have a Fantastic Day! 🙂

You’re welcome
