WordPress 5.9.1

I have deactivated all the plugins and showed all image sizes via wp_get_registered_image_subsizes().

I can see 1536x1536 and 2048x2048. I can't find where these image sizes were registered. Neither in WordPress itself, nor in the theme. Could you comment on it? Where are they registered?

CodePudding user response：

Worpdress registered them in wp-includes/media.php You can remove them:

remove_image_size('1536x1536');
remove_image_size('2048x2048');
