Image Compressor For Wordpress

Skip the plugin — our Image Compressor compresses images before you upload them to your WordPress Media Library, so you don't need a server-side optimization plugin at all.

Use Cases

  • Compressing featured images before adding a new blog post

  • Optimizing product or portfolio images before a bulk media upload

  • Converting images to WebP for faster-loading WordPress themes

  • Reducing hosting storage usage on shared or limited hosting plans

Tips & Best Practices

  • Compress before upload instead of relying on a plugin to do it after
  • WordPress doesn't convert to WebP automatically in most setups — do it yourself first
  • Smaller media library = faster backups and less storage cost over time
  • Featured images especially benefit — they load on every post/archive view
