To edit pictures in a JPEG (.JPG) file, a graphics editor is required. High-end graphics editors include the Adobe Photoshop and Fireworks applications. However, a small, lightweight graphics editor is shipped with all Microsoft Windows operating systems. Microsoft Paint is the graphics editor included with the Accessories program group in Windows. With Paint, the user may edit pictures in a JPG file and save the edited file, or save the file as a different graphic file type.
