Along with GIF, PNG and BMP, JPEG is one of the most common digital image formats. Primarily used for the display of pictures and other complex graphics, JPEG files can range dramatically in size, depending both on the quality of the image and its dimensions. If you need to resize a JPEG to two megabytes or less to comply with upload or disk space limits, adjust the image using Adobe Photoshop, Corel PaintShop Photo Pro or the free Microsoft Paint program included with the Windows operating system.
