Just Image Optimizer

Description

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

FAQ

My image optimization is always “0.00% saved”
  • Please open plugin Settings page. It will check for plugin requirements on your server.
  • If you don’t have any errors on Settings page, then please check logs. You should see that plugin try to optimize at least 1 attachment.
  • Next step is to check that Optimize request URL is accessible by Google Page Speed (just copy it and try to test it with the service).
  • If nothing help, please write to us on Github with screenshots of your Settings page, Log page and last Log details page.
Can I revert original images quality?

To revert original quality of the images, you can use Regenerate Thumbnails plugin.

Just regenerate a single image or all images at once to create new images from the source.

Tried with 5 different google API's keys.. nothing worked.. forever failing to connect. Gave up.

Great plugin and has a nice interface. However, feels like there is need to work on some points at settings page, as it is a bit laggy, but that's not a problem for me. Also, i've tried with 2 different API keys till i got connection saved. With the first API key the plugin didn't want to save options, strange, as it hasn't any restrictions.

Wow! This plugin just helped me get 85 in Google Page Speed. It's really easy to use, flexible and quick. My advise is to use it in pair with Just Responsive Image!
