Avoid possible challenges of PDF format

PDF is a file format used for publishing and distributing electronic documents. Files in PDF format are displayed reasonably close to their paper counterparts on almost any computer, and print reasonably well to almost any printer. If you want to transfer files via email and ensure that your files are readable, PDF format is the safest option. But it can be dead-end as the data, including test, table and graphic contained in it is hard to process, which brings a serious problem for end-users. To guarantee that the document will be viewed correctly one should convert a PDF file into a different format, e.g. TIFF.
