TL;DR:
Want to delete everything from iCloud but don't know where to start? This guide will walk you through the process with simple steps.
Running out of iCloud storage or preparing to switch to a new device? You may want to remove unnecessary files, photos, backups, and other personal data stored in iCloud. However, deleting iCloud data requires some care because synced content may also disappear from your Apple devices.
In this guide, we will show you how to delete everything from iCloud using different methods, including iCloud.com, iPhone/iPad settings, and account deletion. We will also introduce a reliable way to back up your important data before clearing iCloud.

Before deleting everything from iCloud, there are a few important things you should know. Since iCloud syncs data across all devices using the same Apple ID, deleting content from iCloud may also remove it from your iPhone, iPad, Mac, and other Apple devices. To avoid losing important files, keep these points in mind:
Now that you know what to expect, let's see how to delete everything from iCloud in different ways.
If you want to remove data directly from your iCloud account, iCloud.com is one of the easiest options. Although Apple doesn't provide a "Delete All" button, you can delete your synced data by category, including photos, contacts, files, notes, calendars, and more.
Step 1. Open a web browser, go to iCloud.com, and sign in with your Apple ID.
Step 2. Once you're signed in, you'll see different apps that store your iCloud data. Open the category you want to clean up and delete the items you no longer need.

Contacts: Open "Contacts", select the contact(s), click the settings icon or the menu, and choose "Delete".

Photos: Open "Photos", select the photos or videos, then click the trash can icon. (Click here to learn more about how to delete photos from iCloud.)

iCloud Drive: Open "iCloud Drive", select the files or folders you want to remove, and click the trash can icon.

Other data: You can delete notes, calendars, reminders, and other synced content in the same way by opening the corresponding app and removing the items you don't need.
Note: Deleted photos and files are usually moved to the "Recently Deleted" folder, where they remain for up to 30 days before being permanently removed. If you want to free up iCloud storage immediately, empty the "Recently Deleted" folder as well. (No Recently Deleted Notes folder?)
You can also manage your iCloud data directly from the Settings app on your iPhone or iPad. Although there isn't a one-tap option to erase everything, you can remove synced data and delete iCloud backups to free up storage.
Step 1. Open "Settings" and tap your Apple ID at the top of the screen.
Step 2. Tap "iCloud", then select "Manage Account Storage" (or "Manage Storage" on some iOS versions).

Step 3. Choose the data category you want to manage, such as "Photos", "Messages", or "Backups", and follow the on-screen instructions to delete the stored data if the option is available.

Step 4. To delete an iCloud backup, tap "Backups", select your device, then tap "Delete Backup". Finally, tap "Turn Off & Delete" to confirm.

Apple does not offer a one-click option to delete all iCloud data at once. If you only want to free up iCloud storage, you can manually remove different types of data using the methods above.
However, if you no longer want to use your Apple Account and want to permanently remove all data associated with it, you can request account deletion. Please note that this action is permanent and cannot be undone.
Step 1. Visit Apple's account deletion page.
Step 2. Sign in with your Apple ID.
Step 3. Follow the on-screen instructions to review the information and confirm your account deletion request.
