Sprite Sheet Generator

Create sprite sheets from multiple images with JSON metadata, or slice existing sprite sheets into individual frames. Perfect for game development.

Combine multiple individual images into a single sprite sheet with corresponding CSS coordinate data. Upload your icons or animation frames, and the tool packs them into one image file with a JSON or CSS mapping for each sprite's position.

Sprite Sheet Generator: a worked example

A game needs 16 animation frames packed into one sheet with coordinates for the engine.

Input

16 frames (64×64) · 4×4 grid · 2 px padding
Sprite Sheet Generator produces

Output

sprite.png + a JSON atlas of each frame’s x/y/w/h

Packing frames into one image plus a coordinate atlas means the engine loads a single texture and slices it, cutting draw calls and load time. The generated JSON removes the error-prone job of writing frame rectangles by hand.

Frequently asked questions

Why use sprite sheets?

Combining many small images into one file reduces the number of HTTP requests, which can improve page load performance.

What image sizes work best?

Consistent sizes work best, but the packer handles mixed dimensions too. Icons in the 16-64px range are the most common use case.
