Follow the next steps to completely and permanently delete your WordPress.com website.

Fortunately, if you accidentally delete your site or change your mind, WordPress.com offers support to reverse the site deletion. Still, bear in mind that it’s only possible for 30 days after deleting the site. Otherwise, your site will be gone forever.

• Go to your WordPress.com site’s dashboard and click Tools.
• Choose Delete a site (the last item from the drop-down menu).

Before taking any action, export your content. It takes the shape of a zip file.

Scroll to the bottom of the page, read the explanations and click Delete Site.

• Type in the name of the WordPress site you want to delete.
• Click Delete this Site. If you typed in the correct name, the site will be deleted.

• Login to your WordPres.com dashboard.
• Click My Sites > Settings.
• Scroll to the bottom and click Delete your site permanently.

• Export your content.
