Production Ready
Sprite Sheets
The industrial-grade packing tool for game developers. AI-powered animation sequences & icon atlases, MaxRects packing, 15+ engine formats, real-time Godot/Unity sync. All in your browser.
Smart Packing
MaxRects bin packing with heuristic selection. Auto-rotation, transparent trimming, power-of-two alignment, and WebP/AVIF compression for optimized, GPU-friendly sheets.
AI Generation
Two modes: generate animation sequences (walk cycles, attacks, idles) or icon atlases (inventory items, UI elements). Describe it, get production-ready frames.
Animation Preview
Real-time playback with adjustable FPS, onion skin overlay, and drag-to-reorder frame sequencing.
Multi-Export
PixiJS, Phaser 3, Unity, Godot, Spine, Cocos2d, CSS, XML — 15+ formats with engine-specific data files and normal map support.
Engine Sync & Snippets
Real-time WebSocket sync pushes atlas updates to Godot and Unity. One-click loader snippets — paste directly into your project.
Zero Install
Runs entirely in your browser. Auto-generated normal maps, pivot points, filename auto-tagging, and atlas diffing — no signup required for free tier.
Drop or Generate
Drag sprite frames into the workspace, or use AI to generate animation sequences and icon atlases from a text prompt.
Auto-Arrange
MaxRects algorithm packs frames into the tightest possible sheet. Trimming, rotation, power-of-two, normal maps, and compression — all automatic.
