SpriteSpring — Offline Sprite Motion

Got a sprite that feels a little lifeless? SpriteSpring adds quick motion to a PNG without making you draw every frame.

Make it breathe, bounce, sway, react to a hit, spin, shake, squash and stretch, or jump and land. Adjust strength, speed and pivot, then compare the animation with your original sprite.

Try the free demo. Experiment with all eight motions on our little plant, tune every setting and export a real sample sheet. The demo uses only the bundled plant; importing your own images and opening projects are full-version features.

$7 once for the full version. Import your own PNGs and export transparent sprite sheets with JSON frame timing, dimensions and pivot data. Save and reopen projects locally.

Download, unzip and open in Chrome. Works offline. The full version imports static transparent PNGs up to 512 × 512 pixels and 5 MB. Your images stay on your computer; no app account or subscription is needed.

These are whole-image effects: SpriteSpring moves, rotates and scales your existing pixels. It won’t draw new poses or animate individual limbs.

Made by Zero.

Developed with AI-assisted coding.

You may use SpriteSpring for your own personal and commercial projects, including selling projects containing exported animations, provided you have the rights to the input artwork. You may not resell, redistribute, share or sublicense the SpriteSpring tool itself, including its HTML files, source code or download bundle.
