You must be a system admin, team admin, or channel admin to convert public channels to private channels. When a channel is converted from public to private, its history and membership are preserved. Membership in a private channel remains as invitation only. Publicly-shared files remain accessible to anyone with the link.


Default channels such as Town Square and Off-Topic can’t be converted to private channels.

To convert a public channel to a private channel, select the public channel name at the top of the center pane to access the drop-down menu, then select Convert to Private Channel.

From the channel name, you can convert a public channel to a private channel if you're an admin.

Convert private channels to public channels

Due to potential security concerns with sharing private channel history, only system admins can convert private channels to public channels via System Console > Channels > Edit (Channel Configuration).

Alternatively, system admins can perform this action using the mmctl channel modify command.
