Manage link previews
When someone shares a link in Slack, others can see a text preview of the content. Owners and admins can adjust preview settings for websites, third-party files and third-party apps.
Turn off previews for specific websites
Workspace owners and admins can turn off link previews for specific websites.
- Hover over a link shared in the desktop app.
- Click the close icon in the top left to remove the preview.
- Tick the box next to Also block previews from this website in the future and select an option from the drop-down menu.
- Click Remove and block to confirm.
Manage blocked previews
- From your desktop, click your workspace name in the sidebar.
- Hover over Tools & settings, then select Workspace settings.
- Click the Attachments tab.
- Under Blocked previews, review the list of websites with previews turned off. Click the x icon to remove a website from the list and turn previews back on.
Note: On the Enterprise Grid subscription, link previews for websites are managed at the workspace level.
Manage third-party app link previews
Note: App link previews are coming soon. Owners and admins can adjust settings before this feature becomes available.
App link previews let members see key information from their connected apps, such as Jira, Google Drive and more. Owners and admins on paid subscriptions can choose how app link previews will appear for members.
