The game "Minecraft" allows all users to create custom skins for their characters or download pre-made skins and upload them for use. Several skin editors exist and provide all the required tools to create and edit character skins that can then be used inside the game.
Some complete skin editors include Skincraft and SkinEdit. These tools allow users to edit each body part's skin, individually. When the editing process is complete, the skin is saved as an image file. In order to be able to use custom skins, an original copy of the game is required, as the upload process of the skin's image file takes place on the profile page at minecraft.net.
Skin packs are available for purchase on the Xbox and Playstation versions of the game, but not on the mobile version "Minecraft: Pocket Edition".
