Smart Sprite Sheet Packer

Pack sprites into atlas assets for Unity, Cocos Creator, and Godot.

Open tool 6 min read

Sprite Sheet Packer arranges PNG sprites into an atlas, then exports engine-ready PNG + JSON bundles.

Standard workflow

1. Upload PNG sprites, or arrive with slices handed off from AI Sprite Cutter.

2. Manage the item list: rename, select, or remove frames as needed.

3. Set atlas size, padding, naming prefixes, and the target engine (Unity / Cocos Creator / Godot).

4. Review the atlas preview and packing diagnostics, then export the engine ZIP.
