What is the best WordPress image optimizer plugin?

WordPress is home to hundreds of image optimizers and it is rather hard to determine which is the best. Two of our personal favorite WordPress image optimizer plugins are ShortPixel and Imagify.

At this point of writing, both of these plugins offer free and paid plans. Here's more details about them.

ShortPixel. The free plan comes with 100 image optimizations with no size limit per month. Paid plans start at $4.99 per month with 5,000 images optimizations per month and offer both image optimization using a plugin or online.

Imagify. The free plan comes with 200mb worth of image optimizations per month. Paid plans start at $4.99 per month for 1 GB worth of images optimizations (approximately 10,000 image optimization) per month and offer both image optimization using a plugin or online.


Comparison between ShortPixel vs Imagify

Which plugin offers the best image image optimization for WordPress? Let's see the results!

A sample image was downloaded from Unsplash with a size of 1.56mb. Unoptimized image link. For the record, the image compression tests were done outside of WordPress to avoid automatic image compression (via ShortPixel and Imagify online optimization on the web).


ShortPixel image optimization results

ShortPixel comes with 3 methods of image compression namely Lossy Compression, Glossy Compression and Lossless Compression.

  • Lossy Compression. Lossy is the best option for most users. The images processed with Lossy algorithms are the smallest optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you to continue to use Lossy optimization.
  • Glossy Compression. Glossy is the best choice if you still care about Google Insights but you believe that a slight loss of page speed is an acceptable compromise for top-notch image quality.
  • Lossless Compression. Lossless optimized images are pixel-by-pixel identical with the originals, but they offer a smaller size reduction compared to either Lossy or Glossy processed files. If you want your images to remain untouched, then select this option.

Imagify image optimization results

Imagify comes with 3 methods of image compression namely Ultra, Aggressive and Normal.

  • Ultra Compression. This mode will apply all available optimizations for maximum image compression. This will provide huge savings on the initial weight. Sometimes the image quality could be degraded a little. If you want the maximum weight reduction, and you agree to lose some quality on the images we recommend using this mode.
  • Aggressive Compression. This mode provides perfect optimization of your images without any significant quality loss. This will provide drastic savings on the initial weight, with a small reduction in image quality. Most of the time it's not even noticeable. If you want the maximum weight reduction, we recommend using this mode.
  • Normal Compression. This mode provides lossless optimization - your images will be optimized without any visible change. If you want perfect quality for your images, we recommend using this mode. Note: the file size reduction will be less, compared to aggressive mode.
