Why combine PDF files into one

You have multiple PDF documents on related a project, topic or subject. And often, its more of a menace and overhead when searching for a particular phrase as you are bound to open each PDF file. Moreover, it’s particularly frustrating too when sharing your PDF files with others. Because you may have to attach your files as individual attachments in email. Above all, you may have to explain what a particular PDF file is for and does what etc. Under those circumstances, your PDF files would just work better as a single file. Hence, it is better to combine PDF files into one PDF file, which is easier to manage and share, with little or no overheads.
