What Is a Sprite Sheet Generator?

A CSS sprite sheet combines many small images into a single file. Instead of one network request per icon, the browser downloads one image and uses background-position to reveal the right slice for each element. Fewer requests means a faster page, which is why sprites were a staple of icon delivery for years.

This tool lays your uploaded icons into a grid with the column count and padding you choose, sizing every cell to the largest icon so positions stay predictable. Alongside the packed PNG it generates a complete CSS block: a shared base class plus one rule per icon with the correct width, height, and negative background-position, named from each file with a prefix you set.

Sprites suit icons and UI chrome more than large photos; for many projects SVG sprites or icon fonts are the modern equivalent, but classic raster sheets remain widely supported. Everything is packed locally with the Canvas API — no upload.
