Quick Answer
First, check what is using your space: Settings > [name] > iCloud > Manage Account Storage. Then attack the biggest consumers: delete old device backups (often 2-8 GB each), clean your photo library (usually the biggest consumer), remove large iCloud Drive files, clear mail attachments, and disable iCloud backup for apps you do not need backed up. Most users can free 5-20 GB in 15 minutes.
1 Delete Old Device Backups (Biggest Quick Win)
Go to Settings > [your name] > iCloud > Manage Account Storage > Backups. If you see backups from old iPhones or iPads you no longer own, tap them and Delete Backup. Each old backup can free 2-8 GB instantly. This is often the fastest way to reclaim significant iCloud space.
2 Clean Your Photo Library
Photos and videos usually consume the most iCloud storage. Use Swype Photo Cleaner to quickly review and delete unwanted photos — swipe left to delete, right to keep. After deleting, go to Photos > Albums > Recently Deleted and tap Delete All to free the space immediately (otherwise they stay for 30 days).
3 Remove Large Files from iCloud Drive
Open the Files app > Browse > iCloud Drive. Look for large files you no longer need — old downloads, large PDFs, video files. Long-press to delete. Also check the Downloads folder where files from Safari accumulate.
4 Clear Mail Attachments
If you use iCloud Mail, emails with large attachments consume iCloud storage. Open Mail, search for emails with large attachments, and delete them. Empty the Trash folder to permanently free the space.
5 Manage App Data in iCloud
Go to Settings > [name] > iCloud > Manage Account Storage. Review which apps store data in iCloud. Disable iCloud for apps that do not need cloud backup, and delete data from apps you no longer use.
Check Your Results
After cleaning up, go back to Settings > [name] > iCloud to see your updated storage usage. The bar chart shows your new breakdown. Changes may take a few minutes to reflect.
