The settings for TIFF output images using the JPEG compression algorithm
TIFF allows images to be compressed with JPEG (Joint Photographic Experts Group), which is a lossy
compression algorithm. JPEG provides a high compression ratio for
8 and 24 bit images. It is best suited for TIFFs containing
photographs and little or no text.
For the output file name, it is recommended to use the file extension ".tif".
