# Sites That Generate a Preview in Posts

Salesforce provides rich media support for over 400 URLs. When you share a supported link in a post, it’s converted into embedded videos, images, and other types of previews.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col style="width:100%"></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: Salesforce Classic and Lightning Experience</td></tr><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <strong>Group</strong>, <strong>Essentials</strong>, <strong>Professional</strong>, <strong>Enterprise</strong>, <strong>Performance</strong>, <strong>Unlimited</strong>, <strong>Developer</strong>, and <strong>Contact Manager</strong> Editions</td></tr></tbody></table>

Supported preview types include thumbnails, descriptions, and video players for links to videos. If a link doesn’t render as a rich preview, the URL domain isn’t supported or we couldn’t return the preview content.

The list of supported domains includes versions of URLs that third-party shorteners have shortened, like bitly, goo.gl, and tinyurl.com.
