How it works

ImageEngine lets you resize images – FAST. ImageEngine combines three tools into an easy-to-use service. It combines 1) Proactive Device Detection with 2) Image Resizing and 3) a Content Delivery Network (CDN). Just prefix your image source URLs with your ImageEngine account token – or use our WordPress or JavaScript plugins – and we will take it automatically from there. ImageEngine combines image resizing, cropping and compression, with ScientiaMobile’s WURFL mobile device intelligence, and delivers optimized images with CDN-type caching and speed. It also provides full reporting on the performance savings, which frequently results in a 40% reduction of payload size. For more information, see our getting started guide.

ImageEngine Lite

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.

WordPress Plugin

For WordPress site administrators, deploying ImageEngine is even easier. Just install the ImageEngine Plugin, obtain an ImageEngine application token, and insert it into the Plugin settings. The Plugin will automatically optimize all images on your WordPress site and deliver performance improvement.

Plugins, Add-ons, and Modules for JQuery, AngularJS, Ember.js, React.js

We also support several Add-ons and modules for the JavaScript community. With our JQuery Plugin, AngularJS module, Ember.js Add-0n, and React.js Add-on,  you must sign up for the ImageEngine service, obtain an account token, and insert it into the Plugin/Add-on/Module. Once initialized, it will automatically optimize the full-sized original images for devices visiting the website. This will lead to improved image payload and faster performance.

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).

CNAME and customer SSL Certificates

As ImageEngine customers, you can configure the Domain Name Server (DNS) using the CNAME function to rename the ImageEngine service to reflect your own domain/hostname. This renaming of the ImageEngine service allows you to treat the service as if it was managed locally within your infrastructure. This allows for improved caching so ImageEngine cookies will not be presented as third-party cookies. Likewise ImageEngine customers can upload their own SSL certificates through their customer vault. Using these certificates, ImageEngine can use HTTPS to serve multiple domains via the CNAME alias. Both of these features require a non-standard agreement. Please contact our sales for these arrangements.

Help Desk

ImageEngine users receive the same high level of support as other ScientiaMobile commercial products. Customers can submit priority tickets through our enterprise support portal. In addition, users can post and access the responses found on the on the ScientiaMobile customer support forum.
