ImageEngine WordPress Plug-in

ImageEngine wordpress plugin

Boost your web page performance with the ImageEngine WordPress plugin.

ImageEngine is an image optimization service which will automatically resize and optimize the images on your WordPress site. The only thing you need to do is to install the WP ImageEngine plugin from the WordPress plugin directory and register for an ImageEngine account. Read the getting started guide to optimize your images further.

Images are by far the heaviest resources on you web site when it comes to data usage. Now, when mobile is becoming the dominant use case, it is more important than ever to reduce the data traffic and streamline rendering of your web pages. ImageEngine helps you achieve this by applying advanced detection methods while simultaneously applying efficient scaling and optimization operations on every image before it is cached on our CDN.

Once the plugin is installed, it will prefix all image sources, including the new srcset notation supported in WordPress 4.4, with the hostname of the image service. The rest is automatic

Having said that, in the plugin options page, you can tweak a few default settings to your needs:



Automatic compression, resize, format conversion

ImageEngine delivers an image that is automatically optimized based on the device requesting the image. WURFL detects each device’s model and critical capabilities, including its screen dimensions and supported formats. It then automatically compresses, resizes, and changes format to generate an optimized. JPG, BMP, GIF, PNG, and WEBP formats are supported.

Explicit resize and format conversion control

Designers can use ImageEngine’s setting parameters to explicitly control the resizing percent or format conversion for the output image.

Fit Methods

ImageEngine supports several methods that automatically resize an image to fit within specified width and height. These methods (box, letterbox, cropbox, stretch) take different approaches to resizing and cropping to make the image fit.

Image Size and Data Transfers

ImageEngine scales with you.  We deliver billions of images for customers around the world, so we can handle the traffic your sites demand. Users of ImageEngine Lite do not incur monthly charges, but they are limited to individual original images no larger than 2 MB. Likewise, ImageEngine Lite users are limited to a monthly maximum of 5 GB of data transfers, including inbound and outbound traffic.

Commercial License

The ImageEngine license supports different commercial use scenarios (single and multiple domains, enterprise-wide use, intranets, and OEM arrangements). ScientiaMobile can extend pricing to support non-standard commercial agreements that require additional domains (e.g. OEM). Support of CNAME and customer SSL certificates requires a non-standard agreement. Please contact our sales for these arrangements.

Explicit Crop and Rotate

If ImageEngine users want to crop an image in using specific dimensions, then they can use setting parameters to control this. Likewise, ImageEngine supports various angles of rotation.

Full support of Client Hints

ImageEngine supports developers who are using Client Hints to control image resizing. ImageEngine can optimize images based on Client Hints such as DPR (device pixel ratio), Viewport-Width, and Width (device display width).
