Short answer: the most common reason is that the photos were synced from a computer with the Finder, iTunes or the Apple Devices app. iOS doesn't let you delete those on the iPhone, so the delete button is missing or grayed out; you remove them by unsyncing on the computer. Other causes: the photo is in a Shared Album someone else added it to, Screen Time blocks changes to Photos, iCloud sync is stuck, or the iPhone is completely full.
Steps
- Restart the iPhone and try once more. This clears a stuck Photos app.
- Check Settings › General › iPhone Storage. If there's almost no free space, delete an app or downloaded videos first, then try again.
- If only some photos or albums can't be deleted, they were probably synced from a computer. Connect the iPhone to that computer, select it in the Finder (or the Apple Devices app or iTunes on Windows) and click Photos.
- To remove some albums, choose Selected albums, deselect them and click Apply. To remove all synced photos, deselect Sync Photos, click Remove photos, then Apply.
- If the photo is in a Shared Album, open Photos › Collections › Shared Albums. You can delete only what you added; the album's organizer can delete anything.
- If nothing at all can be deleted, open Settings › Screen Time › Content & Privacy Restrictions, find Photos and set it to Allow Changes. You need the Screen Time passcode.
- If deleted photos come back, check sync in Photos › Collections: the status around your account picture shows whether iCloud syncing is paused.
- Once photos delete, empty Photos › Collections › Utilities › Recently Deleted to get the space back.

|---|---|---|
| Delete button missing or grayed out on some albums | Synced from a computer | Unsync them in the Finder, Apple Devices or iTunes |

Photos synced from a computer
Photos that the Finder, iTunes or the Apple Devices app put on the iPhone belong to the computer's sync, not to the iPhone's library. Apple's own help says synced content can't be removed using the iPhone: you deselect it on the computer and sync. iCloud Photos doesn't upload these photos either. If you turn on iCloud Photos, iOS warns you that the synced photos will be removed from the iPhone; the originals stay on the computer.
No app can delete synced photos for you. If you no longer have the computer that synced them, make copies of the ones you want first (save them to Files, or import them to another computer), then connect the iPhone to another computer and sync an empty album or folder to it. A new photo sync replaces the old synced photos, and you can turn photo syncing off afterwards.
Shared Albums and Shared Library
- Shared Albums: participants can delete only the photos they added. The organizer can delete any photo. Photos you saved from a shared album into your library are separate copies: delete those from your library.
- Shared Library: every participant can delete shared photos, but a deletion removes the photo for everyone, and whoever added it gets a notification and can recover it within 30 days. To keep a photo you added but take it out of the shared library, open it, tap ••• and choose Move to Personal Library.
Screen Time and managed iPhones
When Content & Privacy Restrictions are on and Photos is set to Don't Allow Changes, the library can be locked against changes, including deleting. On a child's iPhone, the parent who set up Screen Time has to change it. On a work or school iPhone, check Settings › General › VPN & Device Management: an installed profile may set restrictions that only the organization can lift.
When deleting works but nothing changes
Deleted photos and videos stay in Recently Deleted for 30 days and keep using storage until you empty it (how). With iCloud Photos on, deleting on the iPhone deletes from iCloud and every device too. If you want photos off the phone but still in iCloud, read delete photos from iPhone but not iCloud first.
Doing it with Spaceclear
Cleaner apps delete through Apple's Photos framework, so the same rules apply: Spaceclear can't remove computer-synced photos or other people's shared-album photos either. Once deleting works, it helps with the rest of the library: exact duplicates, similar shots with the best one kept, bursts, screenshots and big videos, all reviewed before anything goes to Recently Deleted. If storage is still full after that, see why iPhone storage is full for no reason.
FAQ
Why is the delete button grayed out in Photos on my iPhone?
Usually because the photo was synced from a computer with the Finder, iTunes or the Apple Devices app. Those photos can only be removed from the computer's sync settings. Less often, it's a Shared Album photo someone else added, or a Screen Time restriction.
Why do my deleted photos keep coming back?
Something is adding them again. Common reasons: iCloud sync was paused and catches up later, another device or a Mac with iCloud Photos still has them, or a computer re-syncs an album each time you connect. Check the sync status in Photos › Collections and the sync settings on your computer.
How do I delete synced photos without the computer?
You can't remove them on the iPhone alone. Use any computer to change the sync: deselecting Sync Photos and clicking Remove photos removes all synced photos. Turning on iCloud Photos also removes them after a warning, but it changes how your whole library syncs, so only do it if you want iCloud Photos anyway.
Why can't I delete photos from a shared album?
In a Shared Album you can delete only the photos and videos you added yourself. The person who created the album can delete anything, or you can leave the album with ••• › Leave Shared Album.
Why didn't my storage go up after deleting photos?
Deleted items wait in Recently Deleted for 30 days. Empty it, then give iPhone Storage a few minutes to recalculate.
