Thus it is advisable to optimize your images without compromising on their quality before uploading them. wordPress Image optimization Plugins can reduce the image size upto 80% without any noticeable change in their quality.

Following are some benefits of Image optimization:

  • Improved Website speed
  • Higher SEO Rankings

Our Recommendations of Image Optimization plugins for WordPress


Following are some of the best WordPress Plugins for image optimization and their features listed for you:
