PDF stands for Portable Document Format. This will make sure that you can send documents that may otherwise take a lot of space. A PDF can also be easier to share because this can be opened in multiple platforms. There is no need to convert various documents anymore so that they will open properly.
For example, have you ever received a file that only comes with a lot of symbols because the document program that you are using does not support the format that was sent to you? Sending a PDF format can help solve the problem. The document will not only be easier to access, but it will also be easier to understand than usual.
