Although Apple has introduced emoji to the iPhone 14 series since iOS 16, it is not a memoji. Memotify.com allows you to create up to six memoji as wallpaper, in three different styles and a variety of colors.

Go to Memotify and choose a memoji from the list or from your own memoji repository.

Select the emoji icon from the keyboard. Then, drag all the way to the left to see memoji. If you don’t have one, you can make your own. You can choose up to six memoji. You can also select from a variety of memoji.

Then you select the desired color. Then select a color type. Then choose the pattern. When finished, scroll down and choose “Create Wallpaper”.
You have the option of previewing the wallpaper you just created. If you like it, you can download it as a wallpaper. Simply hold down on the wallpaper and select “Save Image” at this point.

If you want to change the wallpaper, go to Settings Wallpaper and then select the downloaded wallpaper.

Now this wallpaper is yours.
