Snipshot is an online image editor that provides both a free and paid version. The free service has all the basic stuff for image editing (crop, rotate, resize) and image adjustments (sharpness, contrast, brightness, saturation and hue). On the other hand, Snipshot Pro allows working on RAW pictures aside from being able to use a dozen picture effects and filters. The service also allows for the editing of big-sized or high-resolution photos, importing of PDF files, and has unlimited undo and redo functions. The tools are completely browser-based and no plug-ins are required.
