Spritesheet Tools
Pack sprites or optimize existing spritesheets with deduplication and repacking. Perfect for game development, web animation, and UI sprite optimization.

Packing Options
Space between sprites (prevents bleeding)
Valid range: 256–12288 pixels
Effective Max Sprite Size
With 2px padding, maximum sprite dimensions are: 2044×2044 pixels
(Padding adds 2px on each side)
No Sprites Packed Yet
Upload sprite images and configure packing options, then click "Pack Sprites" to create your spritesheet.
MaxRects Algorithm
Uses the industry-standard MaxRects bin packing algorithm with Best Short Side Fit heuristic for optimal space efficiency (85-95%).
Sprite Deduplication
Pixel-perfect duplicate detection removes identical frames from existing spritesheets, achieving 70-75% reduction on typical game sprites.
Multiple Formats
Export sprite coordinates in JSON, Sparrow XML, CSS, Unity, Godot, Cocos2d formats - all from a single operation.
Atlas Splitting
Automatically splits large sprite sets into multiple sheets when they exceed max dimensions, with full metadata support.
