How can I bulk optimize existing images in my WordPress media library?

There are several effective methods for bulk optimization:

  • Use Imagify plugin for bulk optimization with multiple compression levels
  • Implement EWWW Image Optimizer for server-side optimization
  • Run a bulk WebP conversion
  • Clean up unused image sizes

Before starting bulk optimization, always backup your media library. Consider using a staging environment first to test the optimization settings. Monitor server resources during bulk operations, as they can be resource-intensive. For large media libraries, process optimization in smaller batches to avoid timeout issues.
