Keep large photos sharper
WordPress shrinks uploaded images wider or taller than 2560 pixels. This raises the limit to 3000 pixels, which suits full-width photos on large screens.
<?php
// Pixels. Return false instead to keep the original size of every upload.
add_filter( 'big_image_size_threshold', static fn() => 3000 );
Good to know
Applies to new uploads only.
