Spritix

Spritix is a web-based AI sprite sheet generator that converts a single full-body character image into game-ready animation assets. It supports five actions—Idle, Walk, Run, Jump, and Attack—with output options for 1 or 8 directions.

Workflow

Users first upload a full-body image in PNG, JPG, or WebP format (up to 10 MB), which the system processes into a standardized reference image. They then select an action type to generate. The required credits are displayed before each generation, and credits are automatically refunded if generation fails.

Export Formats

Each action can be exported in four standard file formats:

• Sprite Sheet PNG: A sprite sheet arranged in rows and columns, ready to import directly into engines like Godot, Unity, and Phaser.
• Animated GIF: For previewing timing or sharing for approval.
• Atlas JSON: Contains frame coordinates and timing data for code-driven playback.
• Frames ZIP: A ZIP archive of all individual PNG frames for further editing in pixel art tools.

Loop Editing

Generated animation loops can be adjusted directly in the browser without consuming generation credits. Available controls include trimming extra frames via handles at both ends, running Perfect Loop to automatically find the optimal seam, rotating the starting frame, toggling scaling smoothness, setting playback speed from 0.5x to 2x, and specifying frame count and frame size.

Version Management

Each usable result is saved as a version from v1 to vN, and switching back to previous versions incurs no charge. Characters, actions, versions, and export settings are all organized, and retries never overwrite existing results.

Compatibility

Output files use standard PNG, GIF, JSON, and ZIP formats with no proprietary runtime required. The site lists format compatibility badges for tools such as Unity, Godot, GameMaker, Phaser, Cocos Creator, Aseprite, PixiJS, and Tiled.

Spritix is ideal for game developers who need to quickly produce 2D character animation assets, especially individuals and small teams using the engines or frameworks mentioned above.
