The file format you choose for an optimized image is determined by the color, tonal, and graphic characteristics of the original image. Depending on the file format, you can specify image quality, background transparency or matting, color display and downloading method.

Sliced images should be compressed as JPEG or GIF. Generally JPEG is advisable for photographs as it preserves the quality of the scanned image.

Illustrations with flat color, Sharp edges and Crisp detail should be compressed as GIF files.
