SpriteMachine – Web-Based CSS Sprite Generator (With SASS Support)
CSS sprites are perfect for minimizing the number of requests made to load the images and improving loading speed.
However, for a sprite with many images, it takes time to create the sprite image and the CSS rules.
SpriteMachine is a very straightforward web application for automating the sprite generation process.
Just upload the images in a .zip file, choose the sprite image orientation (horizontal or vertical) and there you are.
One great thing about the app is, it also asks whether the rules generates should be in CSS, SCSS or SASS.
