6 reliable css sprite generators

Sprites aren’t little images but they’re made of one big image.

Essentially, they’re combinations of unlimited number of images formed into one picture. Graphic designers are using CSS image sprites in order to significantly reduce HTTP request.

As they combine all images into a single file, loading time becomes a lot faster.

And with the help of CSS background positioning, it becomes easier to implement individual images.

Unfortunately, this technique can be very time-consuming. This is because you’ll need to manually combine every image that you want to include in a single file.

Then, you’ll have to fiddle with CSS so the images will display properly.

But, guess what? There are free online tools available that you can use to automate the entire process. In this post, you’ll find a collection of tools that let you take your images to generate CSS sprite.
