For example, if you wanted to send someone a report that was spread across several pages, you could combine them into one file to make it easier for the recipient to open and read.

Another reason why you might join PDFs is for archiving purposes. Combining all documents of a project into one PDF makes it simpler for you later on if you need to refer back to them.

In addition, some organizations require their documents in the form of a single PDF. For instance, if you're applying for a job and have multiple documents as part of your application, using a PDF combiner could make the procedure significantly simpler.
