This April, Picnik will be moving its photo editing tools to Google+. For now, you can still use Picnik. They are currently offering Picnik Premium for free. You can currently use Picnik right in your browser. You currently don’t need to download or install anything to use Picnik. Picnik offers a variety of features in their photo editor. One thing I like about Picnik is that you can use the photo editor in your browser.
