Performance Features

Image Optimization

The intelligent image optimization algorithm radically reduces file size without suffering a loss in quality.
You can choose between three levels of image compression.
wao.io optimizes your images by converting the original image into the best matching output format that your customer’s client is capable of rendering.

Lazy Loading

Using lazy loading, your images will be loaded only shortly before they are visible to the user.
Preloading image placeholders in the size of the original images will prevent your site’s layout from jumping around.
You decide which placeholder option integrates best in your overall webpage design

HTTP/2 Upgrade

Enabling wao.io provides an automatic HTTP/2 upgrade for your website.


Your content will be cached in our optimized varnish cache cluster.
In your personal control center you can clear the cache whenever necessary.
