If a channel's conversation is better suited for a closed audience, you can convert the channel to private. This type of channel is best for discussions that shouldn't be open to everyone.

Before getting started

• Only Workspace Owners/Admins and Org Owners/Admins can do this, and they need to be a member of the channel beforehand.
• Files previously shared in the channel will not become private.
• The #general channel cannot be converted to a private channel.
• Shared channels will only be converted in the workspace that makes the change.

Convert a channel to private

Warning: It’s not possible to undo this action. For privacy reasons, private channels can never be made public.

Restrict who can convert channels

By default, Owners and Admins of a workspace or org can convert channels to private (members don't have the option). If they’d prefer, Workspace and Org Owners can limit channel management preferences – including private channel conversions – to only Owners.
