If your iPhone, iPad, or Mac says iCloud storage is full, iCloud backups and syncing may stop updating. The quickest fix is to open your iCloud storage breakdown and remove the largest unwanted category. Photos, messages, backups, and iCloud Drive files are the usual causes.
iCloud storage is separate from the built-in storage on your device. If the warning concerns local device storage, check Settings > General > iPhone Storage or the equivalent option on your iPad instead.
First, Find What Is Using iCloud Storage
Open Settings > [your name] > iCloud > Manage Account Storage. On some older versions of iOS or iPadOS, this option is called Manage Storage.
Review the categories shown, especially Backups, Photos, and iCloud Drive. Delete from the largest category first. You can use the same storage screen from a Mac by going to Apple menu > System Settings > [your name] > iCloud > Manage.
1. Delete Photos and Videos You No Longer Need
Photos and videos commonly use the most iCloud storage. On an iPhone or iPad, open Photos > Recently Deleted, select the unwanted items, tap Delete, and confirm again. On a Mac, do the same inside the Photos app.
You can also select unwanted photos and videos in the main Photos library and delete them. Emptying Recently Deleted is essential; items still there continue using iCloud storage.
- If iCloud Photos is enabled: Deletions sync to your other Apple devices and iCloud. Download the originals to a computer first if you want to keep copies.
- If iCloud Photos is disabled: Photos may be protected by an iCloud backup. Deleting them from a device will not necessarily free iCloud storage.
2. Remove Large Messages and Attachments
Videos, documents, and other attachments can consume substantial space in a few conversation threads.
- Open Settings > General > iPhone Storage or iPad Storage.
- Tap Messages, then select Review Large Attachments.
- Choose attachments you no longer need and tap Delete.
- Open the Messages app, enter an unwanted conversation, and look for Review Large Attachments beneath the contact or group name.
To limit future buildup, open Settings > Messages > Keep Messages and choose 30 Days or 1 Year. On a Mac, delete unwanted conversations from the Messages app. If Messages syncing is enabled, the change can propagate to your other devices.
3. Delete Old iCloud Device Backups
Old backups can take up a lot of room, particularly after changing phones or reinstalling apps.
- Open Settings > [your name] > iCloud > Manage Account Storage > Backups.
- Review the listed devices and identify an old or duplicate backup.
- Select it and tap Turn Off and Delete from iCloud.
This removes the cloud copy of that device backup, not files stored elsewhere. Before deleting the only backup of a current device, connect it to a Mac or PC and make a local backup if you need a recovery copy. An encrypted local backup can preserve Health data.
4. Clean Up iCloud Drive
Files saved through iCloud Drive include downloads, documents, and files from individual apps.
- On iPhone or iPad: Open the Files app, go to iCloud Drive, delete unwanted files, and then empty Recently Deleted.
- On Mac: Open Finder > iCloud Drive, move unwanted files to Trash, and select Empty Trash.
Be careful with Desktop & Documents. If these folders are stored in iCloud, deleting a synced copy from one device can remove it from the others. Download a local copy first if you may need it.
Mac Storage Options: What Actually Frees iCloud Space?
Use System Settings > [your name] > iCloud > Manage to review the same categories available on iPhone and iPad. In Photos, deleting unwanted library items reduces iCloud usage.
- Optimize Mac Storage reduces space on the Mac, not your iCloud subscription.
- Remove Download may free local Mac storage while leaving the file in iCloud.
- Delete the file or conversation is required when the goal is to reduce iCloud storage.
If iCloud Storage Does Not Decrease
- Confirm that every device is signed in with the same Apple ID.
- Allow time for deletions to sync, then reopen the storage screen.
- Empty Recently Deleted on each iPhone or iPad and Trash on the Mac.
- Restart the device if the displayed usage appears stuck.
- Check whether you are using shared family storage. You can only remove content from your own Apple ID.
- If iCloud charges or the available plan do not match your subscription, contact Apple Support.
If an app appears in the iCloud storage breakdown, open that app's settings to remove its saved data. App-specific deletion can erase documents or progress stored only in iCloud.
When Cleanup Is Not Enough
If your remaining files are necessary, open Settings > [your name] > iCloud > Manage Account Storage > Change Storage Plan to compare the free and paid options. An iCloud+ plan can be shared with family members through Family Sharing.
A paid plan adds capacity but does not remove existing clutter. It is usually best to clean up first, then upgrade only if your active photos, backups, and files genuinely require more room.
Best Order to Try
- Check the iCloud storage breakdown.
- Delete unwanted photos and videos, then empty Recently Deleted.
- Remove large message attachments.
- Delete old device backups you no longer need.
- Clean up iCloud Drive and empty Trash.
- Consider a larger plan only if the remaining data requires it.
