What Is Image Sprite Sheet?
A sprite sheet generator that combines multiple images into a single composite image arranged in a grid, along with the CSS background-position coordinates for each sprite. Essential for web performance optimization, game sprite animations, and icon sets. Upload your individual images, set the column count and padding, and the tool generates both the composite PNG and the CSS snippet.

Technical Guide
Images are loaded and arranged in a grid with configurable columns. Row count is calculated as ceil(imageCount/columns). Canvas dimensions are computed from max-width-per-column and total-row-height plus padding. Each image is drawn at its computed grid position. CSS coordinates are generated as negative background-position values for each sprite.
Tips & Best Practices
- 1Use consistent image sizes for a clean grid
- 2Keep padding at 1-2px to minimize wasted space
- 3Name your files descriptively for better CSS class names
- 4Use powers of 2 for game engine compatibility
