The use of PDF files is something that many users do routinely, either because they receive this type of file or because they must be handled in this format for its functionality, security, and compatibility, but one of the frequently asked questions by many users is how merge multiple PDFs into one. This is ideal when reporting from multiple users is required or when the PDFs are part of a sequence of books or series and having everything in one is essential..
In addition, using PDF format ensures that our content will not move or change when we open it from a compatible program as it would with a Word document. If we also have several PDF documents, it will be easier for us to have everything in a single document than to open different ones. TechnoWikis will explain how to join several PDFs into one in both Windows and Linux.
