How can I bulk optimize existing images in WordPress?

To optimize your existing image library in bulk:

  • Install and activate ShortPixel or similar optimization plugin
  • Navigate to the plugin’s bulk optimization section
  • Choose compression level (lossy/lossless)
  • Start bulk optimization process

Monitor the process as it runs, and ensure you have a backup before starting. Many optimization plugins offer free monthly image quotas, with paid plans for larger libraries. For best results, combine with Regenerate Thumbnails plugin to ensure all image sizes are optimized correctly.
