Frequently Asked Questions

Does ImageEngine scale images up?

ImageEngine as an image CDN focuses on optimizing web pages by serving the smallest possible image with the least amount of quality loss. The largest image we will serve is the original image stored in the origin server.

What is an image origin?

An image origin is a place where the original image is stored and served. ImageEngine will cache multiple copies of this original image at our PoPs around the world to ensure that your users get the most optimal image from the most optimal location.

Can I use ImageEngine for native apps?

Yes. ImageEngine can be used in any context where images are delivered over HTTP(S). Read more about ImageEngine and native apps

How is quality affected by image optimizations?

The visual quality - the quality your users see with their bare eyes - is not noticeably degraded. We monitor the visual quality loss programmatically by using the SSIM metric.

How can I point my DNS to ImageEngine?

Can I put Akamai, CloudFront, or Cloudflare in front of ImageEngine?

Usually, it is recommended that ImageEngine serve traffic directly to end-users. However, there are certain cases where ImageEngine can be integrated with Akamai, CloudFront, and Cloudflare. Contact our customer success team to learn more.

Can I use my existing CDN as the origin?

Yes, be sure to check your CDN’s settings and restrictions to make sure that it is allowed through your CDN. Generally, as long as your existing CDN uses stable URLs for images, it is possible. 

How can I purge the cache?

ImageEngine offers a powerful cache purging tool through every user’s account page.

Does ImageEngine have to serve every image on my site?

We understand that every website is unique and different types of images need to be treated differently. We offer a comprehensive tool on our user’s account page that provides a number of User Adjustable Settings to customize image delivery specifically for images meeting various paths.

Please see the Customizing Engine Image Delivery for more information. 

What are the IP addresses of the ImageEngine servers?

As the ImageEngine system of hardware continuously scales up and down. the ImageEngine servers do not have fixed IP addresses.
If your implementation requires a way to authenticate ImageEngine traffic to your origin servers, please reach out to our customer success team for alternatives.

Can ImageEngine serve HTML, CSS, JavaScript, and other assets?

Yes. By default, when serving these types of content we will compress non-image files as Brotli files if the browser supports them.

How many PoPs does ImageEngine have?

ImageEngine scales with the Amazon network by default. Additionally, we also have Points of Presence outside of the Amazon network. The number of PoPs will vary over time as global traffic patterns change.
