Create a sprite sheet from individual images

Adjust columns, spacing, padding, and background before downloading the sprite atlas. Export the optional JSON file for frame coordinates and source dimensions.

Sprite sheet maker FAQ
What is a sprite sheet?
A sprite sheet combines multiple animation frames or game images into one texture. Games can render a selected region of that texture for faster, organized asset loading.
Does PixelPicked upload my images?
No. The sprite sheet is assembled locally in your browser. Your source frames are not sent to a server by this tool.
Can I use frames with different dimensions?
Yes. The packer uses the largest uploaded width and height as the cell size, then centers smaller images without smoothing their pixels.
What does the JSON export contain?
The JSON file contains the PNG name, total sheet size, cell size, and each frame's position and dimensions.
