Almost love your skin, but want to fix the eyes, recolor the outfit, or add one small detail? Use the Skin Editor to change individual pixels.
The editor is made for standard 64×64 Minecraft skins. It does not edit capes, high-resolution skins, or mod textures.
Saving adds a new version and keeps the one you started from. Use the version selector on the skin page to compare or download earlier versions.
If the skin is published, check the version other players will see before sharing the page.
See Creating Player Skins and Publishing Skins.
