WhatsApp is reportedly working on an in-app sticker maker tool to enable users to effortlessly create stickers from their pictures. The feature uses iOS 16 APIs to convert an image’s subject into a WhatsApp sticker. The app would soon introduce a “New Sticker” option within the chat share action sheet which would save a user's time and prevent them from downloading third-party apps for stickers.
