Each of these plugins enhances website performance by reducing image file sizes, improving load times.

Here are some of the best WordPress image optimization plugins to improve website performance:

1. Smush – Compresses images without quality loss; supports bulk optimization, lazy loading, and resizing.
2. ShortPixel – Offers both lossy and lossless compression, with WebP conversion and optimization for existing images.

6. WP Compress – Real-time optimization with cloud-based CDN delivery, adaptive images, and lazy loading.
7. reSmush.it – Free plugin that offers bulk optimization and basic compression control; does not support WebP.
8. TinyPNG (Compress JPEG & PNG) – Optimizes JPEG and PNG images with bulk optimization and WebP conversion.
9. ImageKit.io – Combines image optimization with CDN and real-time transformations, ideal for high-traffic sites.
10. Lazy Load by WP Rocket – Focuses on lazy loading images, enhancing site speed without additional compression.

Each plugin has its unique strengths, so the choice depends on your specific needs, such as CDN integration or lazy loading.

In my experience, the Optimole plugin is the best solution for image compression/optimization, delivery, and lazy loading purposes. I tried Imagify, ShortPixel, TinyPNG, EWWW, and other plugins. But the difference is that Optimole can convert images to WebP or Avif format and serve the most compressed image to the end user. Optimole uses Machine Learning algorithms to automatically find the most optimal version.

Additionally, Optimole delivers all the images through Amazon CloudFront CDN which is the best part I love this plugin.

Also, there is a feature to offload images from the WordPress server and store images on Optimole. This helps to reduce the server disk space too. We can easily transfer them back whenever needed.

The pricing is higher compare to other plugins/platforms. So, I guess this is ideal for medium and large-scale websites/businesses.
