Delete Photos From iCloud but Not iPhone (or the Other Way Around)

iCloud Photos keeps one library in sync across your devices. That’s why you can’t delete a photo in just one place while sync is on: Apple says deleting a photo or video on one device deletes it on every device signed in with the same Apple Account, and deleting it on iCloud.com deletes it from all devices with iCloud Photos on.

Delete photos from iCloud but keep them on iPhone

1. 1

   Step 1: Make room and back up

   Apple says to download your original photos and videos first and make sure your iPhone has enough storage for them. Wait until the download finishes and check that the photos open on the iPhone before you delete anything on iCloud.com. Because the iPhone will then hold the only copy, also copy the photos to a computer.

   Step 2: Turn off sync on this iPhone

   Go to Settings › [your name] › iCloud, tap Photos under Saved to iCloud and turn off Sync this iPhone. Choose Download Photos & Videos to keep a copy on the iPhone.

   Step 3: Delete on iCloud.com

   Go to icloud.com/photos, select the photos, select the Delete button, then Delete. They move to Recently Deleted on iCloud.com for 30 days, and are also removed from your other devices that still use iCloud Photos.

To remove everything from iCloud instead, Apple’s option is Settings › [your name] › iCloud › Storage › iCloud Photos › Turn Off and Delete Photos. It turns off iCloud Photos for your account, and your photos in iCloud are deleted 30 days later; until then you can choose Undo Delete. Download your originals first.

Free up iPhone space but keep photos in iCloud

• Optimize iPhone Storage: with iCloud Photos on, Apple says full-resolution photos and videos stay in iCloud and space-saving copies are kept on the iPhone when needed. Check it in Settings › [your name] › iCloud › Photos (in iOS 27 or later, under iPhone Storage).
• Remove from iPhone: turn off Sync this iPhone and choose Remove from iPhone. The photos stay in iCloud but are removed from the iPhone, and new photos stop syncing.
• Deleting photos on the iPhone with sync still on isn’t a way to keep them in iCloud: they’re deleted there too.

Before you delete

• Recently Deleted: deleted photos stay there for 30 days, and Apple says items in it don’t count towards your iCloud storage.
• Over your iCloud limit: Apple says your device then removes photos you delete immediately, and they can’t be recovered from Recently Deleted.
• Shared Library: if you own one, Apple says to delete it before turning off iCloud Photos for your account.

CleanX

Clean up the library itself with CleanX

If the goal is a smaller library everywhere, CleanX groups duplicate and similar photos and similar screenshots, lists blurry shots, and shows how much space they take. It deletes from your iPhone’s photo library, so with iCloud Photos on, the photos you delete are removed from iCloud and your other devices too, and wait in Recently Deleted for 30 days unless you’re over your iCloud storage limit.

• Duplicate and similar photos grouped, with the space each takes
• With iCloud Photos on, deletes reach iCloud too
• Scanning is free; deleting needs CleanX Pro
