The PDF, or Portable Document Format, was created by Adobe to allow users to read formatted documents on a variety of devices. PDF files can contain text, images and hyperlinks packed into the same document. These documents can be read on a variety of devices, and are meant to preserve the original formatting. The documents can also be edited, but require Adobe’s Acrobat Reader program. This also requires that the document be unprotected. However, editing PDF files is simple and quick. Warnings Writer Bio
