When to use Sprite Generator
- Combine a set of interface icons into one sprite sheet for a prototype
- Reduce the number of separate image requests in a small static site
- Bundle related graphics together with ready-to-copy CSS classes
Important limitations
- Each sprite cell uses one shared size and images are contained rather than individually cropped.
- Generated class names are based on filenames and may need adjustment to match an existing CSS naming system.
Troubleshooting Sprite Generator
A sprite has unexpected empty space
Trim the source image or use assets with similar proportions before rebuilding the sheet.
