BlockSkinLab is an independent collection of free, browser-based Minecraft skin tools for players and creators. Convert an image into a 64×64 or 128×128 skin, generate a random 64×64 AI skin, or edit a 64×64 PNG on a 3D character, then download the PNG with no account. The converter maps your picture onto a skin layout rather than redrawing it with AI. Not affiliated with Mojang or Microsoft.
