To erase a wallpaper on an iPhone running iOS 16 or later, press and hold the Lock Screen to enter the gallery, swipe up on the wallpaper you want to remove, and tap “Delete This Wallpaper.”
That wallpaper you set two months ago is still sitting in the Lock Screen gallery, and every time you swipe between screens, it reminds you how annoying that crop turned out. Getting rid of it takes about six seconds once you know where the delete button lives — which is not where most people first look.
Here is exactly how to erase wallpaper on iPhone, including what to do when the trash icon won’t show up, how to handle iOS 15 and earlier, and why the Settings app will never give you a delete button.
The Only Place You Can Erase A Wallpaper
The delete function lives exclusively in the Lock Screen gallery. Opening Settings > Wallpaper shows your current pair of wallpapers but offers no way to remove old ones. Many people get stuck here and assume deletion is impossible. It is not — the path is just a long-press away.
Apple moved the delete action to the Lock Screen gallery starting in iOS 16. Any iPhone running iOS 16, 17, or 18 has this feature, including the iPhone 8 and every model since. The method is identical across all iOS 18 versions up to 18.5.
How To Erase Wallpaper On iPhone (iOS 16–18)
- Wake the Lock Screen. Press the side button. Do not unlock the phone yet. Alternatively, swipe down from the notch or Dynamic Island on the Home Screen to pull up the Lock Screen.
- Enter the gallery. Touch and hold anywhere on the Lock Screen until the wallpaper zooms out and shows your saved wallpaper collection. Authenticate with Face ID, Touch ID, or your passcode if prompted. Without authentication the gallery appears but the delete option is grayed out or missing.
- Find the right wallpaper. Swipe left or right through the carousel to reach the wallpaper you want gone.
- Swipe up. A single upward swipe reveals the red trash can icon at the bottom of the screen.
- Confirm deletion. Tap the trash can and then tap “Delete This Wallpaper” on the pop-up. The wallpaper vanishes immediately. There is no undo.
Repeat these steps for every wallpaper you want to erase. There is no “Delete All” button — each entry must be removed one at a time. The only wallpaper that survives is the one you keep as your current pair.
What Happens When You Delete — And What Doesn’t Change
Deleting a wallpaper entry removes the Lock Screen/home screen combination from the gallery. It does not delete the underlying photo from your Photos app. The source image stays in your library unless you manually remove it from there too. This also means that if you delete the wallpaper but keep the source photo, you can always set it again later.
The deletion is permanent. You cannot restore a deleted wallpaper configuration if the source image was not saved elsewhere. If the wallpaper was a preset Apple option (like a Stock Still or Dynamic wallpaper), the delete button will not appear for it — you can only replace these with another Apple design.
How To Erase Wallpaper On Older iOS Versions
On iOS 15 and earlier, the Lock Screen gallery does not exist and there is no delete option anywhere in the system. Removing a wallpaper on these devices means deleting the source image file itself.
Open the Photos app, find the image you set as your wallpaper, and delete it from the photo library. The next time the device refreshes its wallpaper cache — usually on the next lock — the old wallpaper will be replaced by the default.
This method is crude but it works on every iPhone back to the earliest models. Just make sure the image is not a photo you want to keep.
Problems That Can Stop Deletion
| Issue | Why It Happens | What To Do |
|---|---|---|
| No trash icon appears after swipe up | You are trying to delete a built-in Apple wallpaper | Replace it with a different wallpaper instead; built-in wallpapers cannot be deleted |
| Trash icon is grayed out | Device is not fully authenticated | Lock the phone, wake it, and authenticate with Face ID or passcode when entering the gallery |
| Cannot long-press the Lock Screen | Phone may have a screen protector or touch sensitivity issue | Use a firmer press and hold the touch for a full second before releasing |
| Wallpaper still shows after deletion | Another copy of the same wallpaper is set as a different appearance (Light/Dark mode pair) | Check both Light and Dark appearances in the gallery — delete each copy separately |
| Delete option does not exist in Settings | Settings app was never meant for deletion on iOS 16+ | Use the Lock Screen gallery method described in the steps above |
| Wallpaper reappears after reboot | Photo Shuffle or a Focus mode wallpaper is still active | Open the Lock Screen gallery, customize the active wallpaper, and remove its photo source |
| Source image deleted but wallpaper remains | The gallery stores a cached copy of the wallpaper | Delete the wallpaper from the gallery using the swipe-up method to clear the cache |
