Nice tool, I use it when I dont want to change or reset my configuration in FastStone Photo Resizer. This just lets me drag and drop and do quick resizes. If you want more powerful options use FastStone.
Other alternatives do not work. I was looking for an app to batch 300+ PNG icons into GIF, preserving quality and transparency. Shrink O'Matic is the only one that can do quality, but the transparency is converted to white background and not black, like the other alternatives.
