Never got time to look for the full form, so please help
"Portable Document Format" is the full name of PDF. PDF is a file format that is extensively used for document creation, sharing, and reading. It was created by Adobe Systems in the 1990s and has now become a standard for electronic documents. One of the primary advantages of the PDF format is that it keeps document formatting and layout independent of the program or device used to read it. This makes it suitable for document sharing that requires papers to be printed or viewed on numerous devices. PDF files can also be protected using password protection, digital signatures, and other security measures to prevent unauthorized access or change.
