To send a TIFF file using wireless means, say through e-mail, it is usually advisable to convert the TIF file to JPG or PNG first before sending the file. The conversion process helps to compress the file, although image quality is usually slightly reduced.
If the file must be sent in the original TIFF format, however, then software applications such as Dropbox and Google drive may be used to send TIFF files from one computer system to another. It is, however, essential for the recipient to have the necessary software to open the TIFF file.
