Portable Document Format (PDF) is the de facto standard for secure electronic document sharing, distribution and archiving.

PDFs are ideal for web and e-mail distribution for the following reasons:

PDF allows anyone to view your documents on any computer, without the need to have the original application the document was authored in.

PDF documents retain the look and feel of the original documents, including fonts, layout, images, links etc.

PDF documents are often smaller than the original document and so are very easy to send to other users.
