About PDF Format

PDF (Portable Document Format) is a file format developed by Adobe Systems for document exchange. It is a common format for sharing documents, as almost any computer or device with a PDF reader can open a PDF file. PDFs are often used for documents such as user manuals, eBooks, application forms, and scanned documents, which can be difficult to edit in other formats. PDFs are also often used to preserve the formatting of a document, so the document looks the same on any device that opens it.
