Picjuice: Quick Online Photo Editor
Picjuice is a web application that allows you to quickly edit your photos. It is powered by Google App Engine, and offers all the standard editing options like crop, resize, flip, rotate, and adjust. The best advantage I saw of this tool was that we don’t need to install any hectic softwares, just for to make small changes to our photos. The only requirement I see is an Internet connection, rest it does not require any addons to work.
After editing, you can save your image in PNG format. The ajaxified user-interface is self explanatory and very easy to use.
