TIFF is a commonly used format for various imaging applications,
including those that scan and fax. Microsoft Office Document Imaging uses the
TIFF format, utilizing the format's capability to contain text
recognized by optical character recognition
(OCR). When you scan new documents, they are saved in TIFF format
(with a .tif extension), and any OCR text is stored in the TIFF file along with
the image.
You can open and edit TIFF files created with Office Document Imaging by using many other graphics applications. When you do so, any OCR text that the file contains is lost. You will have to rerun OCR if you want to access the text in the TIFF file again in Office Document Imaging.
