apply_filters( 'jpeg_quality', int $quality, string $context )

Filters the JPEG compression quality for backward-compatibility.


Description Description

Applies only during initial editor instantiation, or when set_quality() is run manually without the $quality argument.

set_quality() has priority over the filter.

The filter is evaluated under two contexts: ‘image_resize’, and ‘edit_image’, (when a JPEG image is saved to file).


Parameters Parameters

$quality

(int) Quality level between 0 (low) and 100 (high) of the JPEG.

$context

(string) Context of the filter.

    To change JPEG Compression, temporarily add the below code to functions.php then refresh the site to re-compress all thumbnails on the site.

    function my_prefix_regenerate_thumbnail_quality() {
    	return 80;
    
    }
    
    add_filter( 'jpeg_quality', 'my_prefix_regenerate_thumbnail_quality');
