Frequently Asked Questions
What is a sprite sheet for?
A sprite sheet merges many small graphics — icons, buttons, or animation frames — into one image. Loading a single file instead of dozens cuts network requests, which speeds up web pages and games.
How do I use the sprite sheet on a website?
Display the combined image and shift its position with CSS background-position to show just the icon you need. Animation engines work the same way, stepping through frames packed in the sheet.
Does combining images lose quality?
No — each image is placed into the sheet at full resolution. Export as PNG to keep everything lossless with transparency, which is the standard choice for icons and UI sprites.
