Portable Document Format (PDF) is such an important document that it is considered the international standard for information and document exchange. It is used for letters, resumes and even electronic contracts.
PDF was developed by Adobe to make it independent of the device or application it is being viewed on and combines layers of information into one layer thereby making it a flat document.
