GIF always uses lossless LZW compression, but it is always an indexed color file (1 to 8-bits per pixel). GIF discards all Exif data, which because GIF was designed for video screen purposes, GIF does Not retain printing resolution values. GIF was designed by CompuServe in the early days of computer 8-bit video, before 24 bits or JPG was used, for video display at dial up modem speeds.One case is that some camera Raw files are actually TIF format, but with unique proprietary data tags for their special purpose, which then is no longer compatible with TIF viewers. Designers can be assigned special data tags to declare other data and compression types. CCITT data for standard text document storage, which supports multiple pages in one file. There are many TIFF formats for all kinds of data and compressions. Most of the "special" file types (for example, camera RAW files, fax files, or multipage documents) are based on TIF format, but with unique proprietary data tags - making these incompatible unless expected by their special software. For other purposes however, TIF does most of anything you might want, from 1-bit to 48-bit color, RGB, CMYK, LAB, or Indexed color. And TIF is the most versatile, except that web pages don't show TIF files. TIF simply has no JPG artifacts, no additional losses or JPG artifacts to degrade and detract from the original. ![]() The TIF format is not necessarily any "higher quality" per se (the same RGB image pixels, they are what they are), and most formats other than JPG are lossless too.
