What is a PDF Document
A PDF document is a special file format that was developed by Adobe Systems. PDF documents are standardized and free. The PDF document is the file sharing format of today. Whenever you need to share a document to another person, then this document should be a PDF. This will ensure that the recipient who receives the document can open and view it with the exact same formatting as yours. The PDF document contains all the information that needs to be displayed. There are many free PDF Readers. Among other things, PDF24.org has a free online PDF reader available with which you can view PDF documents.
