Enter a Minecraft Java Edition username and click "Load" (or press Enter) to fetch that player's current skin.

Drag the model with your mouse (or finger, on touch devices) to rotate it, and scroll (or pinch, on touch devices) to zoom.

Use the Position tab to fine-tune the pose, scene lighting/background, and held items; Static Renders for flat image exports; and Share to copy a link or download a custom render.

This looks up the player's current skin directly from Mojang, so it always reflects whatever they're wearing right now.
