AI Sprite Animation Generator
Pick a motion, pick a character, get a sprite sheet that loops cleanly and keeps its shape.
Made with this tool
What you get
- A library of ready-made motions with the timing and foot contacts already worked out
- Seamless loops for idle, walk and run
- Clean one-shots for attacks, hits and deaths
- Same palette and silhouette on every frame
- Exports PNG + JSON, GIF, frames ZIP, Godot SpriteFrames, Aseprite JSON
- Custom motions from a text description when the library doesn't have it
How it works
- 1Bring a character: generate one, reuse an earlier one, or upload your own sprite.
- 2Choose a motion from the library and a frame count.
- 3Download the sheet with frame data, or send it straight to your engine format.
Great for
Walk and run cycles for platformers
Attack, hurt and death sets for action games
Idle breathing loops for menus and NPCs
Spell and ability animations
Guide
Why AI sprite animation usually looks wrong
The common way to animate a sprite with AI is to ask a model for every frame. Each frame is a fresh guess, so the sword changes length, the cape changes color, the feet slide and the loop never quite closes. You end up cleaning every frame by hand, which defeats the point. Our approach is different: every motion in the library comes with locked timing and planted foot contacts, tested before it went live. When you animate a character, it follows that motion instead of inventing movement from nothing, and the finished frames are checked one by one before you download them.
Loops and one-shots
Idle, walk, run, fly, swim and climb are loops: the last frame flows back into the first, so you can play them forever. Attacks, hits, jumps, rolls and deaths are one-shots with a clear start and end; the death animation holds on its last frame. The generator shows each motion's frame count and suggested frame rate, and the exported JSON marks the frames you will want for gameplay, such as the release frame of a spell or the impact frame of a punch.
Frame rate and timing
Pixel animation usually runs between 8 and 12 frames per second, much slower than video. Lower frame rates look snappier and more deliberate; higher ones look smoother but cost more frames. Our motions come with a suggested FPS that matches how they were timed, and the editor lets you preview any rate before export. In Godot and Unity you can set the playback speed per animation, so you can tune it in-engine without regenerating.
Exporting to your engine
Download a PNG sprite sheet with JSON frame data, an animated GIF for previews, a ZIP of individual frames, a Godot SpriteFrames resource, Aseprite JSON or TexturePacker / Phaser JSON. Sheets are evenly spaced with no padding surprises, so Unity's Sprite Editor grid slicing and Godot's AnimatedSprite2D importer pick them up on the first try. Remember to set texture filtering to nearest or point so the pixels stay crisp.
FAQ
Why does a motion library beat generating every frame?
When a model invents every frame independently, arms change length and feet slide. Every motion in our library has its timing and foot contacts worked out and tested before you use it, and every animation is checked frame by frame before you get it. That is why our loops close and the character keeps its shape.
Can I animate my own existing sprite?
Yes. Upload your sprite as the character and pick a motion. Matching your sprite's size and view gives the best result.
How many frames do I get?
Most motions come with 6 to 12 frames at a suggested frame rate. You can trim, reorder or change the FPS in the editor before exporting.
What does an animation cost?
10 credits per motion per direction, shown on the button before you generate.
