PDF Format Introduction:

PDF (Portable Document Format) file extension name is *.pdf. PDF is a file format used to represent documents in a manner independent of application software, hardware, and operating systems.

Invented by Adobe Systems and perfected over 20 years, PDF is now an open standard for electronic document exchange maintained by the International Organization for Standardization (ISO). When you convert documents, forms, graphics, and web pages to PDF, they look just like they would if printed. But unlike printed documents, PDF files can contain clickable links and buttons, form fields, video, and audio — as well as logic to help automate routine business processes. When you share a PDF file, virtually anyone can read it using free Adobe Reader software or the Adobe Reader mobile app.

Businesses and government agencies around the world use PDF as a standard format for exchanging documents more securely. Using security features, including password protection, you can help prevent people from accessing, copying, editing, or printing PDF documents. You can also permanently delete sensitive information from PDFs by redacting visible text and illustrations or removing hidden information.
