WHAT IS SHEET CREATOR?
Sheet Creator is a browser-based, high-performance texture packing tool. It takes individual image frames and intelligently compiles them into a single, optimized Sprite Sheet (Atlas). By consolidating images, it drastically reduces memory usage, draw calls, and load times in game engines like Unity, Godot, and Phaser.
HOW IT WORKS
1. Upload Sprites
Drop your individual frames or prop images into the workspace.
2. Choose Algorithm
Select 'Basic Grid' for sequential animations or 'MaxRects' to tightly pack distinct items of varying sizes to save maximum memory.
3. Configure Bounds
Add pixel padding to prevent texture bleeding, and enable Alpha Trimming to crop out invisible empty space around your sprites.
4. Export & Integrate
Download the final optimized PNG alongside a native JSON data file (Unity, Godot, or Phaser format).
SETTINGS GUIDE
Algorithm
Choose between 'Basic Grid' for sequential uniform frames, or 'MaxRects' to optimize space for varying sprite sizes.
Sprite Padding
Adds transparent pixels between frames to prevent color bleeding when your game engine scales or anti-aliases the texture.
Trim Alpha (MaxRects)
Automatically crops out the transparent empty space around each sprite before packing, maximizing atlas density.
Extrude Edges
Duplicates the outermost colored pixels of each sprite, preventing visual tearing and artifacts in 3D rendering engines.
JSON Format
Selects the coordinate data structure. Formats are natively optimized for Unity, Godot (Rect2), Phaser 3 (Array), or Generic (TexturePacker Hash).
