How can I bulk optimize existing images in WordPress?

To bulk optimize existing images in your WordPress media library:

  • Install an optimization plugin
  • Access the bulk optimization feature
  • Select compression level
  • Run the optimization process

The Imagify plugin is excellent for bulk optimization. It offers three compression levels (normal, aggressive, and ultra), WebP conversion, and can resize images upon upload. The plugin provides detailed statistics about space saved and maintains image quality according to your settings. For best results, backup your media library before running bulk optimization.
