This extremely common cross-platform format was created by the Joint Photographic Experts Group as both a type of file compression and a file format. JPEG images contain raster images that have been compressed to a fraction of their original size on disk, making them an excellent choice for saving animations. K-3D loads all known variations of JPEG files, and saves files using a variable quality setting ranging from 0 to 100% that controls the size and quality of the saved image. 0% will create the smallest file size, but compresses the file so much that the image may not be identifiable as having come from the original. 100% creates much larger files, but creates files that are visually indistinguishable from the original, and can still compress the file down to one-twentieth the size of the original. When saving JPEG files, you will need to experiment with different quality settings to determine which gives you the best tradeoff of file size vs. image quality.
