Im searching for a function php code to adapt or compress avatars (profile, group) and covers.

I found this, but only works with WP Media and rtMedia uploads.

// Increase Image compression in WordPress
function wt_handle_upload_callback( $data ) {
    $image_quality = 75; // Change this according to your needs
    $file_path = $data['file'];
    $image = false;

    switch ( $data['type'] ) {
        case 'image/jpeg': {
            $image = imagecreatefromjpeg( $file_path );
            imagejpeg( $image, $file_path, $image_quality );
            break;          
        }

        case 'image/png': {
            $image = imagecreatefrompng( $file_path );
            imagepng( $image, $file_path, $image_quality );
            break;          
        }

        case 'image/gif': {         
            // Nothing to do here since imagegif doesn't have an 'image quality' option
            break;
        }
    }

    return $data;
}
add_filter( 'wp_handle_upload', 'wt_handle_upload_callback' );
add_filter( 'wp_editor_set_quality', function( $quality ) { return 75; } );
