About Sprite Lab
Sprite Lab 🧪 is a universal 2D sprite sheet generator designed to help game developers and artists efficiently pack individual sprite images into a single, optimized texture atlas. Version 0.4 introduces enhanced packing algorithms, support for multiple image formats (PNG, JPEG, GIF), and flexible export options including JSON and XML data files. The tool features automatic trimming, rotation, and configurable padding to minimize wasted space and prevent texture bleeding. Its intuitive interface allows batch processing, custom sprite sorting, and real-time preview of the generated sheet. Sprite Lab streamlines the workflow for any 2D project, from character animations to tile maps and UI elements.
Use Cases
- ▸Generate a sprite sheet from character animation frames when building a 2D game
- ▸Create a tile map atlas when designing levels for a platformer or RPG
- ▸Combine UI elements into a single texture when developing a mobile or desktop application
- ▸Optimize sprite memory usage when deploying a game to resource-constrained devices like mobile or web
Features
- ✓Imports individual sprite images in PNG, JPEG, GIF, and other common formats
- ✓Automatically packs sprites into a single sheet with customizable padding, rotation, and trimming
- ✓Exports sprite sheets with accompanying data files in JSON and XML formats
- ✓Supports batch processing to generate multiple sheets from folders or lists
- ✓Provides a real-time preview of the sprite sheet with zoom and pan controls
- ✓Allows custom sorting, naming, and grouping of sprites within the sheet
