What is a GIF sprite sheet?

A sprite sheet lays out all frames of an animated GIF as a grid in a single PNG image, commonly used in game development and CSS animations.

What format is the sprite sheet exported in?

PNG. This format preserves all colors and transparency from the original GIF frames.

How do I control the grid layout?

Set the number of columns. The number of rows is calculated automatically based on the total frame count.

How do I use the sprite sheet in CSS?

Use the `background-position` and `animation` properties to step through frames. Each frame occupies (width × column, height × row) pixels in the sprite.

Can I use sprite sheets in games?

Yes. Game engines like Phaser, Unity (2D), and Godot all support sprite sheets for frame-by-frame animation.

What are the dimensions of each frame in the sprite sheet?

Each cell equals the original GIF dimensions. The total sprite sheet size is (gifWidth × columns) by (gifHeight × rows).

Does the sprite sheet include transparency?

Yes. PNG supports full alpha transparency, so any transparent areas in GIF frames are preserved.

Is my original GIF modified?

No. The sprite sheet is a new PNG file. Your original GIF is read but not changed.

Why would I use a sprite sheet instead of a GIF?

Sprite sheets allow precise control over animation — you can pause, reverse, or jump to specific frames using CSS or JavaScript, unlike auto-playing GIFs.
