Since Instagram doesn’t let you delete your account within the app itself, you’ll need to log on to Instagram via a web browser. Once you do, follow these steps to delete your Instagram account permanently.
Go to the “Delete Your Account” page.
In the “Why do you want to delete [account name]” section, choose the reason you are deleting your account.
Re-enter your Instagram password.
Click the “Delete [username]” button.
