To delete stickers on an iPhone, follow these steps:

1. Open the Messages app and go into any conversation.
2. Tap the plus (+) icon on the left side of the screen.
3. Select the "Stickers" option to open your sticker gallery.
4. Make sure you are in the "Live" tab (which looks like a peeling sticker), not the "Recent" tab.
5. Long press (touch and hold) the sticker you want to delete until a menu or animation appears.
6. Tap "Delete" or "Remove" from the options that show up to permanently delete the sticker from your collection.
7. Repeat for any other stickers you want to remove.

You can also delete multiple stickers at once by long pressing a sticker and choosing "Rearrange," which allows you to tap a delete (⊖) button for each sticker you want to erase

. If you want to remove stickers from the emoji keyboard, open the emoji keyboard, go to the "Live" tab, long press the sticker, and select "Delete"

. For stickers added by third-party apps, you can hide or remove the entire sticker pack by deleting the associated app or hiding the pack in the Messages app

. If the remove option does not appear, ensure your iPhone is updated to iOS 17.1 or later and try restarting your device

. This method works for custom stickers created from photos, Live Photos, Memoji, and generative AI stickers on iOS 17 and iOS 18 and later
