Frequently Asked Questions

A CSS sprite is a single image file that combines multiple smaller images (usually icons). It reduces HTTP requests, improves page load speed, and simplifies icon management. By using background-position in CSS, you display only the needed part of the sprite.

Manual sprite creation is tedious. Our tool offers drag-and-drop, real-time preview, customizable layout, spacing, background, and exports clean CSS. It works entirely in your browser – no uploads to a server, keeping your icons private.

Copy the provided CSS code and include the sprite image in your project. Each icon gets a unique class (based on your prefix). Add the common sprite class to an element and the specific icon class to set its background position and size.

Yes! Choose PNG for lossless quality and transparency, or WebP for smaller file sizes. You can also set a custom background color, including transparent (use rgba(0,0,0,0) or transparent).

No hard limit, but performance depends on your device. We recommend combining up to 50 icons for smooth experience. The canvas generation handles large images efficiently.

Absolutely. The tool is fully responsive; you can upload images from your phone gallery and adjust settings on the go. The preview adapts to screen size.
