TIFF - Tagged Image File Format
Is one of the basic file types File Juicer can extract from other files. It is usually a lossless image file format, which can have compressed data.
It can contain previews in JPEG format and EXIF tags, which File Juicer can extract. TIFF is used as the basis for some camera vendors RAW file formats, but in those cases it does not have the tif extension as they have added their own additions to the format.
