Frequently Asked Questions
What is a sprite sheet?
A sprite sheet is a single image file that contains multiple smaller graphics (sprites). It is widely used in 2D game development and web design to manage many small assets efficiently.
Why should I use a texture atlas generator?
Using a texture atlas generator online free helps in reducing memory overhead and improving rendering speed. Instead of the browser or game engine loading 50 separate images, it only loads one, which is much faster.
Does this tool support JSON coordinates?
Yes! Our online sprite sheet maker automatically generates a JSON data file alongside the image. This file contains the precise location and size of every sprite within the sheet.
Can I use this for CSS sprites?
Absolutely. You can create CSS sprites online free by packing your UI icons and using the generated coordinates in your CSS `background-position` properties.
Are my images uploaded to any server?
No. This is a secure sprite sheet maker no upload. All processing occurs locally on your machine using your browser's capabilities.
