SpriteLoop – Free 2D Animation Tool

SpriteLoop is a free 2D animation tool for Windows, Mac and Linux for creating animations from a collection of images, a style known as cut out animations. In many ways it’s a free but limited version of popular animation tools like Spriter and Spine.

Features of SpriteLoop include:

• Import PNG parts and animate them with position, rotation, scale, skew, opacity, pivots, and parent-child links.
• Import SpriteLoop data packages exported from external tools with preserved part order, positioning, visibility, and opacity.
• Build cut-out animation rigs using hierarchical transforms.
• Inherit position, rotation, scale, and skew through the transform hierarchy.
• Create multiple animation clips with custom FPS, frame count, and looping settings.
• Automatic loop interpolation for seamless repeating animations.
• Add, move, copy, paste, duplicate, and edit timeline keyframes.
• Choose interpolation per keyframe: Linear, Stepped, Ease In, Ease Out, or Ease In-Out.
• Preview animations with playback controls, zoom, pan, and onion skinning.
• Use skew animation to create simple perspective and isometric-style effects.
• Create character skins and reusable visual variations without duplicating animations.
• Add part variants to swap hairstyles, clothing, equipment, colors, and other character elements.
• Store part visibility per skin.
• Resize the canvas, set background colors, and use guide frames for export framing.
• Save self-contained .spriteloop project files with embedded PNG assets.
• Export spritesheets, PNG image sequences, GIFs, or animated WebP files.
• Optimized atlas generation with automatic reuse of identical images.
• Includes a Defold runtime extension for playing SpriteLoop animations directly in Defold projects.
• Runtime support for skin switching and part variant swapping in Defold.
• Select a default skin directly from the Defold editor.
