How to make a sprite sheet

Combine animation frames or game sprites into one packed sheet — the format game engines load most efficiently. Runs in your browser.

Steps

1. Add frames in order. The first frame's size sets the cell size; other frames are drawn into cells of that size.
2. Set columns (optional). Leave it at 0 to auto-pack into a roughly square grid, or set an exact column count for a strip or fixed layout.
3. Generate sheet & download. You get a single PNG with all frames laid out left-to-right, top-to-bottom.

Tip: keep every frame the same dimensions for clean, predictable cells.
