How can you delete WhatsApp group without admin?

It is not possible for a non-admin user to delete a WhatsApp group directly. Only the group admin has the privilege to delete the group. However, if you no longer want to be a part of the group, you can follow these steps to leave the group:

1. Open WhatsApp on your device.
2. Go to the group chat that you want to leave.
3. Tap on the group name at the top of the chat screen.
4. Scroll down and tap on "Exit Group."
5. Confirm that you want to exit the group by tapping "Exit" again.

Once you leave the group, you will no longer receive any messages from the group. If you want to delete the group completely, you need to request the group admin to delete the group. If the group admin also leaves the group, another participant who has been in the group the longest will become the new admin and will have the privilege to delete the group.

If you are the only member left in the group apart from the admin, you can ask the admin to remove you from the group, and then the admin can delete the group.
