WP ImageEngine Responsive Image Resizer

WP ImageEngine is an intelligent image CDN for optimizing, compressing, resizing and delivering images according to the screen- or viewport size.

WP ImageEngine is an intelligent image CDN for optimizing, compressing and resizing images. ImageEngine will enhance your responsive images by enabling support for HTTP2, automatic webp conversion, Client Hints and more.

It is likely that ImageEngine will shave off 50-60% of data traffic generated by images on your site. To better support mobile devices, ImageEngine relies on WURFL for server side device detection in cases where responsive images and Client Hints fall short.

The plugin will automatically optimize the images you include in your posts and pages. For images baked into your theme, there is a php API available (See FAQ).

Registration is required to get the most out of ImageEngine. There is both a completely free option, and a commercial option.

Responsive Images Support

WP ImageEngine is compatible with the changed <img> tag introduced in WordPress 4.4, while still providing full support for older versions. For WordPress version 4.4 and above the plugin will optimize every version of the image referenced in srcset. ImageEngine will prefix your image srcset and src (URI) with your personal hostname which refer to the image optimization servers.

Client Hints

The plugin will enable Client Hint support for your site. Client Hints, with information about the viewport size, device pixel ratio and actual image size, are added to the image request (HTTP header) enabling ImageEngine to resize the image with surgical precision.

HTTP2 support

HTTP will give additional performance improvement on the network level. WP ImageEngine supports HTTP2 over SSL, which means that if you serve your sites and images by https://, ImageEngine will automatically serve all images over HTTP2.

WebP

WebP is a lightweigh image format with great quality. WebP is well supported by browsers. ImageEngine will detect if the end user's browser supports WebP and automatically convert any format to WebP to increase performance.
