Easy Image Optimizer


Want to get more visitors and customers? Easy Image Optimizer allows you to quickly and easily speed up your website so that you can connect with more people.
One-click activation enables you to optimize your images by efficiently encoding and properly sizing images. It also includes lazy loading to defer offscreen images and automatic WebP conversion for even more speed.

Easy Image Optimizer will optimize your site automatically by replacing all your image URLs with cloud-based URLs to deliver your content as fast as possible.
Beyond image optimization, it will also speed up the delivery of your CSS, JS (JavaScript), and font resources, by minifying them and delivering them through a speedy CDN (Content Delivery Network).

Часто задаваемые вопросы

Does the plugin replace existing images?

No, all optimization is performed transparently on our network of cloud servers, and your image URLs are automatically updated to point to the optimized images.

What if something breaks?

Don’t panic, just disable the plugin and contact us at https://ewww.io/contact-us/ All changes made by the plugin will automatically be reverted when you disable the plugin.


I am really impressed by the service provided by EWWWI. My website was very slow and I chose to trial Easy IO. After running a speed test, my website speed has improved by 70%. A huge improvement. I have since added a second website of mine to Easy IO. I find the customer service fast to response to every query and they go beyong expectation by providing other useful tips to help me with my website.
