Sprite Sheet Maker — Pack Images into a Texture Atlas

Combine any number of separate images into one optimized sprite sheet. Choose bin packing (tight, space-efficient — best for mixed sizes) or a simple grid (uniform cells — best for animation frames), set maximum atlas dimensions from 256 to 8192 pixels, control the padding between sprites, and pick a transparent or solid background.

The result downloads as a PNG plus JSON metadata listing every sprite's name and position — generated entirely in your browser, with a checkerboard preview so you can see exactly what's transparent.
