Description

The Portable Document Format is a universal document format developed by Adobe. It is a cross-platform standard, which allows documents to be displayed and printed the same way on multiple computers, regardless of the platform.

PDFs can be created with Adobe Acrobat and viewed with the free Acrobat Reader. They are also supported by several third-party programs, which can be used to view and export PDFs. Most Web browsers include the Acrobat plugin, which allows PDFs to be viewed directly in a browser window.

PDFs may contain text, images, forms, and other data. They can also be secured using a password or a digital signature.
