About this tool
Game Engine Integration Guide
Sprite sheets are the industry standard for 2D game rendering because they reduce GPU draw calls:
- Godot Engine: Import the PNG as an
AnimatedSprite2Dwith SpriteFrames or Sprite2D with Hframes/Vframes. - Unity: Set Texture Type to Sprite (2D and UI), Sprite Mode to Multiple, and slice with Automatic or Grid by Cell Size.
- Phaser 3: Load via
this.load.spritesheet('anim', 'spritesheet.png', { frameWidth: W, frameHeight: H, margin: P, spacing: P }), where P is the gap you chose (use 0 for both if you set the gap to 0).
Common questions
Frequently Asked Questions
Does the exported sprite sheet retain transparency?
Yes. Any transparency in the original GIF is preserved on the transparent PNG canvas.
What is included in the JSON coordinate download?
A TexturePacker-style JSON hash: meta.size holds the sheet width and height, and frames has one entry per frame (frame_0, frame_1, …) with its exact x, y, w, h rectangle and its delay in milliseconds taken from the GIF.
Is there a limit on GIF length or frames?
You can process animations with dozens of frames since all processing is accelerated on your local hardware.
