Image optimization plugin support

Hello

I’d like to continue a closed thread that was started at this URL: https://wordpress.org/support/topic/webp-conversion-support/

1. I’ve been using the Imagify plugin for several years to optimise images. The problem is that I can’t get it to work nicely together with the Better Image Sizes plugin. I tried a few approaches with AI using the bis_image_created hook, but I either got no results or ended up with a 500 error. Do you know any way to make these two plugins work together?
   
   Here’s the code that doesn’t work for me:

/**
 * Auto-optimize BIS images with Imagify after generation.
 * Hooks into 'bis_image_created' to trigger Imagify optimization immediately.
 */
if (!function_exists('wp_bis_imagify_auto_optimize')) {
  function wp_bis_imagify_auto_optimize(int $attachment_id, string $bis_file_path): void {
    // Check if Imagify is active and the class exists
    if (!class_exists('Imagify\Optimization\File')) {
      return;
    }
    
    // Check if file exists
    if (!file_exists($bis_file_path)) {
      return;
    }
    
    // Check if Imagify API is available and configured
    if (!function_exists('get_imagify_option') || !function_exists('imagify_valid_key')) {
      return;
    }
    
    if (!get_imagify_option('api_key') || !imagify_valid_key()) {
      return;
    }
    
    // Get Imagify settings
    $optimization_level = get_imagify_option('optimization_level', 1); // Normal by default
    $backup = get_imagify_option('backup', false);
    
    try {
      // Create Imagify File optimization instance
      $file = new \Imagify\Optimization\File($bis_file_path);
      
      // Check if file can be optimized
      if (!$file->is_supported()) {
        return;
      }
      
      // Optimize the file (creates WebP/AVIF automatically based on Imagify settings)
      $result = $file->optimize([
        'backup'             => $backup,
        'optimization_level' => $optimization_level,
        'context'            => 'custom-folders', // Mark as custom folder
      ]);
      
      // Log errors if optimization failed (optional)
      if (is_wp_error($result)) {
        error_log(sprintf(
          'Imagify BIS auto-optimization failed for %s: %s',
          $bis_file_path,
          $result->get_error_message()
        ));
      }
    } catch (\Exception $e) {
      // Silently fail - don't break the image generation
      error_log(sprintf(
        'Imagify BIS auto-optimization exception for %s: %s',
        $bis_file_path,
        $e->getMessage()
      ));
    }
  }
  
  // Hook into BIS image creation
  // causing error 500
  add_action('bis_image_created', 'wp_bis_imagify_auto_optimize', 10, 2);
}

2. Do I even still need Imagify, now that the https://wordpress.org/plugins/images-to-webp/ plugin is available? If my images in WordPress are not optimised enough, this plugin will always convert them to .webp and create a well-optimised version. Maybe the Better Image Sizes + Images to WebP setup is good enough as a solution?
