Select your group’s title at the top of the screen to visit its profile page.

• Alternatively, you can long-press the group’s name in the “Chats” tab, tap the three-dot menu icon in the top-right corner, and from the following dropdown, head into “Group Info” to view the group’s profile page.

• Navigate to “Group Settings.”

• Here, you can adjust what kind of rights admins and participants of a group have.
• Select the “Edit Group Info” option to specify which set of members can modify the group’s basic details.

• In the pop-up window, switch to “Only Admins.” Tap the “OK” button to save the new preference.

• Now, only the admins can edit your group’s information and profile picture.
• As soon as you put this change into effect, WhatsApp will notify the group’s participants about it with a note in the conversation. The option to edit the group’s name, description, and icon will simply disappear 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” pop-up.

There are also other, similar perks that WhatsApp group admins can take advantage of. For instance, admins can revoke participants’ ability to send messages in a group chat if, for instance, they’d like to broadcast an important announcement and don’t want it to get buried under the deluge of other chatter.
