PDF files are one of the most popular document types. They’ve got their own reasons for being so popular, and one of them is the ability to combine two PDF files.

Probably that’s why you’re searching for answers to questions like How to combine PDF files, how to combine two PDFs, combine multiple PDFs, or anything related to that. And that’s exactly what this piece is all about as well.

But before that, let’s start by diving into the details of PDF files a bit.

What are PDF Files?

PDF is the abbreviation for “Portable Document Format”. Now why it’s so popular might be a mystery to many, because we all are familiar with and use PDF files, but seldom do we care to dig into such technical details.

The reason PDFs are so popular is, they’re almost like a standalone document format. Meaning, if you run any document using Ms-WORD, it needs extra fonts, graphics, and other elements, doesn’t it?

Well PDF doesn’t. It encompasses within itself each and every element needed to display the document.

So what happens is, it doesn’t matter if you use custom fonts, custom graphics or anything else, they won’t be lost when you share the file from one system to another which might not have that specific font, because the PDF file stored the font within itself when you created the file.

Also, it doesn’t matter if you created the file on Windows XP, Windows 7 or any other operating system, you can run it seamlessly anywhere as long as it’s a PDF document.

Now that was the “common man, English definition” of what a PDF is. If  I get into technicalities, codes and the “magic number” which is used with a PDF file, you might break your computer screens.

And anyway this is a piece on combining PDF files, so let’s not go beyond the scope of this article.

What does Combining PDFs Files Mean?

Before I can start with the piece on how to combine PDF files, it’s only fair of me to explain what combining exactly means.

When you combine two PDFs, what basically happens is, one PDF file will merge with the other.

So, first of all, you’ll get one single file in place of two different PDF documents. And secondly, the contents of one PDF will be merged with the content of the second PDF.

In other words, it’s copy-pasting the data of one PDF to that of another.

Why Combine PDF Files?

So now you know what PDF files are, and what combining them means. The only question that remains to be answered is, why would you want to combine PDF files?

There are quite a number of reasons why you might want to combine your PDF files, let’s have a basic glimpse at some of them:-

  • Ease of sharing. Obviously, combining two PDF files makes them one, hence you can E-mail, share over WiFi or any other way send it to other colleagues easily.
  • Reduces confusions:- It’s no use having 10 different PDF files for different chapters of the same book or something related. Instead, they all can be merged in one file for better understanding.
  • Hiding documents:- This isn’t a common reason why people combine PDF files but trust me it works. It’s easier to search and find one file in a dump of PDFs, but it’s comparatively harder to search for one page of the document if it’s hidden with a separate 100-page PDF document, right?

Anyway, that’s enough chit-chat, let’s get down to business.
