PDF is an extremely popular format for storing and sharing documents. It’s incredibly versatile. You can fill up a PDF document with various content – text, images, charts, tables – create complex layouts, add hyperlinks and so on. If you need to print out a document, its digital version should definitely be in PDF; then you will get great results. Also, it’s quite easy to view PDFs – you literally only need a browser for it. On top of all that, one of PDF’s main advantages is that it’s very safe and secure because it’s quite hard to edit; in some cases, it’s not even possible to copy any text in a PDF document!
