Frequently Asked Questions
Explore comprehensive answers, technical specifications, and helpful guidance for organizing and managing your documents.
What is a CSS Sprite sheet?
A CSS Sprite is a technique that merges multiple images or icons into one single image file. By using CSS background-position, you display specific parts of that image, reducing network requests.
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.
Are my uploaded icons safe?
Yes, processing is entirely browser-side. No files are uploaded to any server, keeping your graphics completely private.
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>.
