How to use additional domains

On this page

Your Sirv account can serve images from multiple domains/subdomains, enabling you to personalize your file URLs. For example, you could serve images to different websites, with each site having its own custom image URLs.

Add more domains from the Settings page of your Sirv account:

Add additional domains

Custom domain and domain

Additional domains are configured as a subdomain of e.g. The name can contain letters, numbers and hyphens (6-32 characters length).

Your additional domain can also point to your own domain e.g.

Additional domain details

To configure a custom domain, add a CNAME record via your domain name control panel. Refer to the CNAME setup instructions if you need help.

Custom folders

Each additional domain can be configured to point to a particular subfolder of your account. (By contrast, your primary domain can only point to your root folder).

Let's say you had a custom domain of, you could map that to a specific folder such as /arkwright in your Sirv account. An image located at /arkwright/example.jpg would be served from

Custom profiles

Each subdomain can have its own Default profile. The Default profile contains the standard settings applied to all your images. A different default profile could be used to apply a watermark to images from a certain subdomain or change the TTL file caching time or any of the other 100+ default settings.

Before setting a different default profile for a subdomain, create a new profile in your Profiles folder, with the custom default settings you wish to have.

SSL certificate

All additional domains and their custom domains will receive a free SSL certificate, so files can be served over HTTPS. This will be automatically renewed by Sirv for as long as you keep using it.


Additional domains are charged at $5/month.
