The Portable Document Format or PDF is one of the most common file formats used by consumers today. PDFs were first launched in 1993 by Adobe Systems. Earlier, internet users did not have an easy way to format information and exchange it with others in a secure way.The arrival of the PDF solved this issue. The secure PDF comes with a two-dimensional layout that enables the content to remain static, no matter which operating system the document was created in or consumed on.
While these developments have made PDFs more popular, it has also led to the need to lock & protect your PDF.
