If you've made the decision to leave WhatsApp, either as a result of limited storage space, you can delete your account permanently.

Before proceeding make note that deleting your WhatsApp account is absolutely irreversible. Once you delete it, every single message will be erased, including multimedia files. It's crucial to save any messages before taking this step.

To delete your WhatsApp account, follow these steps:

1 Start by opening WhatsApp on your phone or accessing the WhatsApp website using a desktop browser.

2 Tap on the settings icon on your phone, located in the top-right corner of the browser window.

3 Select 'Settings' from the menu, to open the settings panel.

4 Navigate to the 'Account' section, and look for the 'Account' section.

5 You'll find an option that says 'Delete my account.'

6 You'll be prompted to enter your phone number to confirm the deletion of your account. Type in your phone number and tap on 'Delete my account.'

7 WhatsApp will then ask that you want to delete your account. Be aware that you can't recover anything, and you won't be able to log in again using the same phone number after deletion.

After following these steps, your whatsapp web account will be deleted completely, and you won't be able to log in again using the same phone number.

Note that if you've used WhatsApp Business or WhatsApp with multiple numbers, deleting one account won't delete all of them. In this case, you'll need to delete each account separately.

The simple act of deleting the app doesn't delete your account, so you can still delete your account even if you've removed the app from your phone.
