Portable Document Format (PDF) is a worldwide standard for electronic documents. It was originally developed by Adobe for the U.S. Federal Government to store its legacy files. Now PDF files are used by government, regulated industries, different financial services, lawyers, publishing industry, education institutions. PDF files are used to distribute faxes, documentation, handbooks, court filing, letters, reports, tax forms.
PDF file preserves all the fonts, colors and structure regardless of the software and hardware so the electronic copy of PDF document will be always identical to the original and it will be viewed and printed identically to the original document.
PDF documents can be viewed on more than 20 hardware platforms (including Windows, Linux, Unix, Mac, Palm and Pocket PC) using freely distributed viewers like Adobe Reader.
Moreover, PDF format meets the legal documents requirements. It means that PDF file can not be altered without leaving electronic footprint. In addition to this, PDF files provide document-level security (using 40-bit or 128-bit key) and they can be protected by the password. Content of the document can be protected from editing, copying and printing as well.
Images, watermarks, hyperlinks and annotations can be embedded into the PDF document. Ability to use tree-like structured bookmarks (outlines) makes the navigation much easier.
PDF documents can contain interactive elements like input fields, listbox, checkboxes, radioboxes. That is why PDF is widely used as the PDF forms that can be filled in, printed or electronically submitted from web-browser. PDF files are compressed so they can be downloaded much faster and their storage takes much fewer resources.
