Stop making extra image sizes

WordPress stops making the 768px, 1536px and 2048px copies of every image you upload. Saves disk space; your theme’s own sizes are still made.

Type PHP
Runs Everywhere (runs as WordPress loads)
Category Media
Tested with WordPress 7.1

PHP

<?php

add_filter(
	'intermediate_image_sizes_advanced',
	static function ( $sizes ) {
		unset( $sizes['medium_large'], $sizes['1536x1536'], $sizes['2048x2048'] );
		return $sizes;
	}
);

Good to know

Only affects new uploads. Responsive images use the other sizes, so phones and big screens still get a fitting copy.

Install it in one click

It's already in the Snipfire plugin's library. Enter your site's address and it opens there, ready to install. It arrives switched off, and Snipfire checks the code and test-loads your site before you switch it on.

Needs Snipfire on that site and you logged in as an administrator. Your address stays in this browser; we don't see it. Get Snipfire free

Or add it by hand

Click + New and choose PHP.
Paste the code and give it a name.
Where: Everywhere (runs as WordPress loads).
Save and switch it on.

Works in any snippet plugin, or a child theme's functions.php. Without the safety net, though.
