Free web based power of 2 sprite generation tool

I've developed a free web based retina/SD sprite generation tool that works for creating sprite textures for mobile and web projects and I thought I'd share it with the Unity community. It works with individual sprite images (i.e. an exported set of animation images) that you insert on the page and it then generates the sprite based on a number of options. As far as features for Unity projects, it can generate sprites in power of 2 sizes (i.e. 32x32, 256x256, etc) and has a setting for alphanumeric ordering so if you have a series of sprites that are numerically named, it will order based on that.

It also outputs a JSON file that can be integrated into a Unity project so that you can integrate the sprite into a script and easily handle future modifications to the sprite.

Not sure if scratch an itch for anyone but I wish I had something similar when I was building my sprites. I'm also open for feedback or feature requests.
