Q.What is a CSS Sprite sheet?

CSS Sprite Generator FAQs
Answers to common queries about image sprites, CSS embedding, and performance benefits.
Q.Does merging icons improve site speed?
Yes. Loading one 50KB image is much faster than loading twenty 2KB icons because it eliminates the overhead of multiple HTTP requests and network latency.
Q.Are my uploaded icons safe?
Yes, processing is entirely browser-side. No files are uploaded to any server, keeping your graphics completely private.
Q.How do I use the generated CSS?
Download the sprite sheet image, load the CSS stylesheet in your project, and add HTML elements with the base class sprite and the specific icon class, e.g., <span className="sprite sprite-home"></span>.
