Web server

Any web server which is accessible over HTTP or HTTPS can be configured as an origin in This allows you to use's real-time image optimization and transformation features on all existing images.
Note: We do not start copying images from your server as soon as you add it. Instead, we will fetch the particular image when you request it through URL-endpoint. Learn more to understand how this works. The images accessed from this origin will not appear in your Media library.

Step 1: Configure origin

  1. 1.
    Go to the external storage section in your dashboard, and under the Origins section, click on the "Add origin" button.
  2. 2.
    Choose Web server from the origin type dropdown.
  3. 3.
    Give your origin a name, it will appear in the list of origins you have added. For example - Website load balancer.
  4. 4.
    Fill out the base URL, for example, if your current image URL is, then enter as the base URL.
  5. 5.
    Leave the advanced options as it is for now.
  6. 6.
    Click on Submit button.

Step 2: Access the image through URL-endpoint

When you add your first origin in the dashboard, the origin is by default made accessible through the default URL-endpoint of your account. For subsequent origins, you can either create a separate URL-endpoint or edit existing URL-endpoint (including default) and make this newly added origin accessible by editing the origin preference list.
Let's look at a few examples to fetch the images:
So when you request, internally fetches the file from

Step 3: Integrate and Go live

Advanced options for web server origin

Include canonical response header

When enabled, the image response contains a Link header with the appropriate URL and rel=canonical. You will have to specify the base URL for the canonical header.
For example, if you set as the base URL for canonical header, then the image response for URL will have a Link header like this:
Link: <>; rel="canonical"

Forward Host header to this origin

By default, when tries to get the image from your origin, the value of the Host header is the same as the base URL specified for the origin. For example, if the base URL is, then the same gets forward to your origin.
However, when this setting is enabled, the host value from the image URL will be forwarded to the origin as the Host header. For example, if you are using a custom domain name for your image URLs, like , then that is what gets forwarded to your host instead of

Whitelist request from

If you have deployed a WAF, you need to whitelist requests coming from servers.
We recommend you to whitelist our requests to your origin based on request header value. All our requests to your origin will have a header x-req-from with its value set to imagekit.
Below is a list of IP addresses currently used by to fetch images from your origin:
Note that these IP addresses are subject to change in the future. Any changes will be reflected and updated in this document.
