Portable Document Format was created by Adobe. It has become a globally standard for sending and saving digital files. These days, it is the most reliable document sort that can be read on any computer and on any smartphone without having jeopardizing format or quality. PDFs can contain written text, images, spreadsheets, or any sort of details.
A PDF file is just like a printed document but in digital form. As opposed to hard copies, a PDF can have built in video and audio files, as well as links to jump instantly to other areas of the document or additional resources. You can even set up safety to avoid unwanted reading, printing or document editing.
