My Fast CSS Sprite Generator

I've been working on a CSS Sprite generator for a couple of weeks in my spare time. It uses HTML Canvas and JavaScript FileReader to open local images without any zipping or uploads, and tries to make the CSS generation as easy as possible. I made it because it is a tool that I wanted to have, and I am hoping to get some feedback from others now that it is functional. http://instantsprite.com

In plain words

My Fast CSS Sprite Generator is a browser-based tool for creating CSS sprites from local images. Users drag and drop images onto the page, arrange them, set CSS classes, and export the sprite sheet in multiple formats. The tool runs entirely in the browser using HTML Canvas and JavaScript FileReader, requiring no uploads or file compression. It is designed for web developers who need to combine multiple images into optimized sprite sheets for faster website loading.
