CatSkinC is a lightweight, client-side Minecraft mod that makes uploading and switching skins quick and seamless.
Unlike the vanilla system, CatSkinC supports HD skins up to 4096×4096, instant previews, and changing your look without restarting the game.
It is designed for players, artists, and communities who want more customization and flexibility than Mojang’s default skin service.

CatSkinC is an independent skin system, completely separate from Mojang’s official skin service.
It does not replace or modify your Mojang account skin. Instead, it works as an alternative client-side option for those who want HD skins, instant switching, or more flexibility.
Your official Mojang skin will remain untouched — CatSkinC simply gives you another way to express yourself.
