Navigate to ‘Group Settings’.
Here you can adjust what kind of rights administrators and participants of a group have.
Select the “Edit Group Info” option to specify which group members can edit the basic information of the group.
In the pop-up window, switch to ‘Admins only’. Tap the “OK” button to save the new preference.
Now only the administrators can edit your group’s information and profile picture.
As soon as you make this change, WhatsApp will notify the participants of the group with a note in the conversation. The option to edit the group’s name, description, and icon just disappears from members’ phones.
To restore the original settings, you can return to the same “Group Settings” menu and switch back to “All Participants” in the “Edit Group Info” popup window.
There are also other similar benefits that WhatsApp group admins can take advantage of. For example, admins can revoke participants’ ability to send messages in a group chat if, for example, they want to broadcast an important announcement and don’t want it overwhelmed by other chatter.
