TweenPose Studio

TweenPose Studio is a free, browser-based tool for animating 3D models exported from Paint 3D. You open a .glb file and pose its separate parts, such as the torso, arms, legs, and head. Then you set keyframes on a timeline and shape the motion with an easing graph, so movement can ease in and out instead of being stiff. It exports the finished animation as transparent PNG frames or a GIF, so you don't have to pose and save each frame by hand.

Key features:

• Keyframe timeline with a drag-to-edit easing curve
• Parent parts together (arms follow the torso) and move each part's pivot point
• Snapping, fine-adjust sliders, and undo/redo
• Cloth and wind physics for thin, flat parts like capes and flags
• Auto-backups and saveable project files
• Nothing to install and no account needed
