Change the Big Image Size Limit
Sets the size above which WordPress scales down very large uploaded images (2560 pixels by default), for example to 1920 pixels to save disk space and bandwidth.
Opens WPIDE on
Code
// Longest side in pixels before an uploaded image is scaled down.
$wpide_big_image_threshold = 1920;
add_filter( 'big_image_size_threshold', function () use ( $wpide_big_image_threshold ) {
return max( 600, (int) $wpide_big_image_threshold );
} );Notes
The original file is kept on the server; WordPress uses the scaled copy everywhere. To turn scaling off completely use the Disable Big Image Scaling snippet instead.
