With SpritePad you can create your CSS sprites within seconds. Simply drag & drop your images and have them immediately available as one PNG sprite + CSS code. No fiddling in Photoshop, no manual assignment of CSS styles.
Drag & drop image files onto the space below, or use the “Open” link to load images using the file browser. Then, click “Generate” to create a sprite sheet and stylesheet. This demo uses a couple of HTML5 APIs, and it is only compatible with modern browsers.
