🔸 Description The Portable Document Format (PDF) is a file format used to present documents independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. In addition, group 3 eliminates redundant data during compression to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can significantly lose image quality.
