What is a PDF file?
The PDF file was developed by Adobe Systems who intended to design a file format that can be displayed the same way on every computer. Today the PDF is the number one file format for sharing documents. Invoices, for example, are always received as PDFs. The PDF stands as the final result. Subsequent modifications are not possible. The file format was not designed for that purpose.
Opening and viewing a PDF file
You can open a PDF file with a PDF reader. An example of a comprehensive program is Adobe Reader. However, there are a variety of other PDF readers that you can open a PDF file with. Today you can also open a PDF file without a PDF reader. Most browsers are already equipped to support PDF files, so you can easily open a PDF file using a browser.
