# Favicon per Domain

In the Domain Mapping System settings, select the "Upload Image" button next to any mapped domain to set a custom favicon for that mapped domain:

![Upload Custom Favicon Per Domain](/files/cxvcMtjFUWYh1BPPO9y7)

{% hint style="danger" %}
Be sure to clear your browser's local cache after making this change, otherwise, you may continue to see the old favicon. 
{% endhint %}
