Have you ever had the task of combining two files and alternating each page in an interval, finding yourself confused in the middle of the process? We can just imagine the pain of going through that task physically and mentally, which is why we’re showing you an easier way on how to do this easily through digital means. But first, let’s tackle a few things about PDFs.

Can you change the page order of a PDF?

Unlike other document processing software like Word or PowerPoint, PDFs are not meant to be easily edited and changed. This is actually why most printing or publishing companies prefer this format than others. In Word, you can simply hit “enter” and paste the copied content in between or after the first document. This easy manipulation has certainly added convenience but it has also been the source of trouble for some. It could lead to the wrong alteration caused by human error.

Why do you need to alternate PDF pages?

Usually, this dilemma comes from scanning books, having separate files that are in odd and even pages. Users scan odd and even pages separately out of convenience and efficiency but combining it as one becomes a difficult task. Your typical PDF viewer won’t cut it though, in fact, you will probably need a special tool that will help you edit or change anything. This is where DeftPDF comes in.

How to alternate pages of combined PDF

Mix the pages of two or more PDF files by alternating a number of pages from each one. Let’s say you wish to include 2 pages per file before it alternates to the next file, you can do so with DeftPDF tool. The tool can also configure a different number of pages per file and reversing the order of files. Here’s how you can do it:

Step three: Input the “1” on the box asking for the “switch documents after reading _ pages.” This indicates the number of pages that you need from the documents before it switches to another. Then choose regular or reverse order, whichever is necessary. Selecting reverse order starts the inclusion of the pages from the last.
