JPEG
The JPEG image format is a common file format for storing pictures since it offers highly compressed color images with minimal loss of visual fidelity.
JPEG is considered "lossy" in that the full quality of the original image is not preserved in favor of higher compression ratios.
The JPEG Quality setting can be set from 1-100 to provide the desired ratio of file size to quality.
JPEG can also be used for documents but the compression works better with pictures. Very small text can often be blurred by JPEG compression and become illegible.
MRC compression in PDF files overcomes this limitation by applying different compression techniques to pictures and text within the same page. This gives much smaller files without loss of quality.
SimpleIndex also supports output to JP2 or JPEG 2000 File Formats. This is an updated version of JPEG that provides much better quality and smaller file sizes.
TIFF images support both the JPEG-6 and JPEG-7 embedded compression format.
