Just Image Optimizer

It’s the only plugin that will help you pass Google Page Speed image size optimization test. Furthermore, it compresses image file size, so you get a performance boost and improve your page rank in Google.

The plugin uses Google Page Speed Insights API to optimize images. All you need is a Google console account and an API key.

Image Optimization runs in the background on Google servers, so the site will keep its performance intact. There are no special server requirements.

Requirements

• Site should be available for Google Page Speed test
• PHP 7
