It is always possible to use PDF files at some point if you share documents online, as it is the most secure file format. However, in the course of using PDF files, it is also possible that you may need to merge PDF files for many reasons. Most people merge PDF files to streamline their documents.

The most important thing is to understand how to merge PDF files. Fortunately, there is a way out, and this article will present the best tool to show you how to merge two PDF files. The question is, how do we merge PDF documents? You’ll need a PDF merge app – and PDFelement for iOS is one of the best. The following are the steps to merge PDF files using this app.

Part 1. Why Merge PDF Files on iPhone

For several reasons, you may need to combine multiple PDF documents into a single file on your iPhone or iPad. Consolidating everything into one PDF can make organizing, sharing, and referencing important information much more accessible.

Some common scenarios where merging PDFs is applicable include:

  • Combining source materials. If you have downloaded or received several PDF documents related to a research project or work assignment, merging them into a single multi-section PDF file helps keep all the source materials together.
  • Compiling reports/presentations. Need to share a lengthy report or presentation deck? Merging all the component PDF sections into one file makes it simple to send or upload as a complete document.
  • Travel documents. When traveling, it’s convenient to merge all your PDFs, like boarding passes, hotel reservations, directions, etc., into one file for easy access.
  • School/university. As a student, consider consolidating course materials, lecture slides, notes, and assignments from multiple PDFs into a single PDF for each class for better organization.
  • Contracts/agreements. If you need to fill out or sign a multi-part PDF contract or legal agreement, merging the files first helps ensure you get all the sections.

So, in many situations, combining PDF files seamlessly on your mobile device can save time, reduce confusion, and make sharing or referencing information much more efficient.
