PDF files, or “Portable Document Format” files, are a type of document created to allow documents to be displayed a certain way regardless of the computer or device from which they are being read. They can be viewed on many devices in a variety of programs, and can be read and edited as the user sees fit.

The encryption process is simple and requires only access to your PDF file in Adobe Acrobat Reader. Warnings Writer Bio
