Why is Knowing How to Combine PDFs Essential?

April 2, 2019

How to Merge PDF

Almost every PDF software program provides users with the function “Merge PDF.” This feature is a standard in many programs that can edit PDF documents and is quite helpful.

Nevertheless, as our experience has shown, not everyone uses this feature. Why? Well, some people just don’t really need it. But many simply aren’t aware of the benefits of combining PDF documents.

Due to ignorance, some people even prefer an old-school workaround: printing the PDFs on paper, rearranging them as desired and later scanning them to send them back. Not very smart time-wise, nor very environmentally friendly.

Therefore, we decided to shed some light on how, why and when you may want to combine PDFs as well as the process for combining PDF files.

Benefits of Combining PDF Documents

Sharing Data with Ease

When you need to upload or attach several documents, problems may arise. While most email services and social networks enable users to attach multiple files, some platforms still have a one-file limit.

For instance, you may want to email your resume, recommendation letter, portfolio, and some certificates, but are only allowed one file attachment at a time; what will you do? What is your strategy for handling multiple file uploads?

Combining your files into one PDF document is one of the easiest solutions. There’s no need to send each document separately, you can just merge them into a single document and upload it seamlessly to whatever platform you need.

Easy Document Management for Large Projects

Large projects often require multiple teams and a great number of documents including plans, change requests, progress reports, and so on.

Individuals, teams, and departments, are often required to provide routine reports regarding tasks, goals, and stats.

How can you efficiently manage all of those reports without wasting time searching for this or that document?

To showcase all the results and conclusions, it may be a good idea to combine the various reports into one big file available for every team.

If you consolidate several reports into bigger PDF documents structured according to aspects such as data, department, task, or goal, it will reduce the number of files necessary and make the search process much faster.

You won’t need to work with several files for presentations or emails, just use one PDF document with all the necessary information and skip the hassle.

Faster and Smarter Printing

There are two possible scenarios for needing to print out numerous documents:

I. You click open your files and send them to print one by one. 
II. You merge your files into one in few clicks and print it out in minutes.

Option one really only serves as an exercise in patience. Instead of wasting time clicking away and losing track of what’s already printed and what you have left, print once and dedicate your valuable time to more important tasks.

Scanning and Merging

If you scan a large quantity of content such as a 30-page contract or several pages out of a book, you’d definitely prefer it to be one file. However, errors or technical issues can interrupt the scanning process.

What do you do if the scanning process was interrupted? Simply save the pages you have already scanned and keep scanning. When you’ve finished, combine all of your files into one PDF.

Combining PDFs on Windows, Mac, and Linux

How to Combine PDFs on Windows

If you are a Windows user, an optimal solution is to use Adobe Acrobat DC. It’s an all-encompassing and time-tested software program for editing your files.

Not only can you combine your existing PDF files, but you can also convert and merge Word, Excel, PowerPoint, audio files, video files, and even web pages into one PDF document.

Before you create the final document, you can preview it, change the order of pages, and delete any unnecessary pages.

If this sounds like what you need, check out the free trial of Adobe Acrobat DC before paying for one of the available plans.

The process of combining with Adobe Acrobat DC is the following:

  1. Download and install the software.
  2. Select Tools and then Combine Files.
  3. Click Add Files and upload the files you want to combine.
  4. Rearrange, delete, and preview pages.
  5. Click Options and choose smaller, default, or larger file size depending on your needs.
  6. When you’re finished arranging the pages, just click Combine.
  7. Save your document by clicking File>Save As>Location of File.

One problem you may face while trying to merge PDF files with Adobe Acrobat DC is speed. When you open large PDF files such as books, the software works much more slowly.

Another disadvantage that many users complain about is the price for the paid version of Adobe Acrobat DC. If you find it rather pricey, you can try out other free Windows-based alternatives that may have fewer features but are just as helpful when it comes to combining multiple PDF files.

Finally, Adobe Acrobat DC is not always as reliable as you could think and even vulnerable. Unless you regularly update it, you may put at risk the security of your data. This is a common issue in many companies with employees that got used to the old version and keep using it.

It is a must to update the software to reduce security risks. If you would like to avoid spending time on constant updates, perhaps, it is better to stick to web applications that maintain everything for you and lower security risks almost to zero.

How to Combine PDFs on Mac

Mac offers some practical built-in tools for editing and viewing content that Windows lacks. Application preview is one of its hidden gems. So, if you are a Mac user, you don’t need to buy, download, or install anything to merge PDFs.

Here’s a brief guide on how to merge PDFs with the Preview app:

  1. Open all the files you want to combine in the Preview app.
  2. Open the View menu for each document and click Thumbnails to see page thumbnails in the sidebar.
  3. Drag and drop individual page thumbnails or the whole PDF document into another thumbnail to combine them and create a single document.
  4. You can use the Shift key to select a continuous range of pages or the Command key to select page thumbnails from anywhere in the file and add them to other files.
  5. Use the toolbar to arrange pages. You can reorder pages as well as rotate them. If you have any pages you don’t need in the final document, you can also delete them.
  6. When the document looks good and is well-structured, make sure to save it. Choose File > Export as PDF and save the merged PDF file. Note: There are upsides and downsides to the Preview app. You can drag any PNG, JPEG, or any other standard image format into the PDF file, but you cannot drag web pages, Word files, or Excel files directly into your PDF. This is why sometimes there is a need to resort to third-party options like Adobe Acrobat DC.

How to Combine PDFs on Linux

If you want to merge PDFs on Linux, the process can be a bit different from doing it with a Mac or Windows interface, but it’s not any more complicated. If you know the steps, it will take you just a few minutes to combine any files you want to even if they’re scattered in different folders.

We will cover a few methods you can use to combine your PDF files on Linux.

PDFtk Tool

Pdftk is a handy tool if you want to merge PDF files and organize data in one document. Install PDFtk as shown below.

apt install pdftk

When the installation is complete, you can start combining documents. For instance, if you have two PDFs you want to make one, just run the following command:

pdftk file1.pdf file2.pdf  cat output merged_output.pdf

PDFunite Tool

Pdfunite is a part of a PDF rendering library called Poppler-Utils. So, to install Pdfunite, first you need to install the Poppler-Utils package as shown below.

apt install poppler-utils

Once you have it installed, you can start merging your files. If, for example, you have three documents in the directory, the command will be: 

pdfunite file1.pdf file2.pdf file3.pdf merged_output.pdf

It’s as simple as that.

PDFSam

If the methods mentioned above do not appeal to you, PDFSam is the best alternative. This desktop application has three variants: Basic, Enhanced, and Visual. PDFSam Basic has more than enough features necessary to combine your PDF documents.

The steps for combining your files are the following:

  1. Download and install PDFSam.
  2. Open the app and click Merge on the left column.
  3. Then click Add button on the right column.
  4. Select your PDF files.
  5. Arrange your PDF files by selecting a PDF and clicking on the arrow buttons to move the file up or down.
  6. Name your new document and select the destination folder.
  7. Click Run.
  8. Your PDF is ready! You can now check it out in the folder you selected for it to be saved.

With PDFSam you can also split, rotate, and extract pages. If your needs go beyond what is offered with these features, you can upgrade to PDFSam Enhanced or Visual for a wider range of options.

Other methods: Ghostscript, Using Convert tool

Key Takeaway:

The main benefit of combining PDFs through desktop software is the ability to work offline without relying on your Internet connection. If you’re willing to spend some time on installations and software updates, then this method will work well for you.

How to Combine PDF Files On Mobile Devices

If you have an urgent need to share an item in one document, you don’t necessarily have to run to your laptop.

There are some user-friendly applications available that can help you combine PDFs on-the-go from your mobile device. Regardless of whether you are an Android, iPhone or Windows Phone user, there is a solution for you.

Merge PDF Files on iPhone and iPad

If you need to combine files to make one document on an iOS-powered device, there are several applications on the Apple Store that will allow you to do this. PDFelement and PDF Expert are some of the most popular apps available to help you out.

PDFelement is a robust application that allows you to make a variety of edits and, of course, lets you merge your PDFs. After just four simple steps and a few minutes of your time, your document will be ready.

  1. Download and launch the app.
  2. Import your PDF documents to the local list.
  3. To enter the editing mode, tap the icon in the upper right-hand corner.
  4. Select all the files you need and tap the Merge button at the bottom of the screen.
  5. Finally, you can save the PDF document, open it in another application or share it.

Another way to merge and edit your PDF on an iPhone or iPad is by using PDF Expert. It helps create professional-looking documents that can be easily shared with your colleagues, boss, clients, or friends.

Combining with PDF Expert is a breeze, just three steps and you’re done.

  1. Install and open the application.
  2. Tap Select at the top and choose the files that you want merged.
  3. Tap the Merge button.

You can annotate and edit your PDF as well as create outlines and bookmarks with the help of PDF Expert.

Merge PDFs on Android

With Android, can also be breezy with the right tools. We recommend PDF Suite. It is one of the most reliable apps we’ve seen with a variety of features including combining PDF, and it works without hidden prices and other inconveniences common with this software. Here are five simple steps to merge your documents into one PDF file.

  1. Download and install the PDF Suite application on your device.
  2. Open the application and select the Merge PDFs option.

Merge PDFs on Windows Mobile Devices

If you are a resilient Windows Phone users and you’d like to merge your PDFs asap, you have several options available. We recommend Ultra PDF Editor. This is an advanced multifunctional application that offers a great number of editing opportunities.

However, if you only need to combine your files there is a standard course of action just as there is for all the previously mentioned Android and iOS solutions.

  1. Install and open the application.
  2. Tap the Merge option on the left side of the screen just below the Fill Form feature.
  3. Select and add files by tapping the +Add Files button.
  4. If you need to, you can reorder pages or remove any unnecessary files.
  5. Save the PDF document.
  6. After the document structure is set, you can use tools to highlight and underline text, add comments, and use a freehand-writing or drawing tool.

Key Takeaway:

Mobile applications come in handy when you urgently need to edit and use a PDF document, or sometimes just to skip the hassle of downloading a desktop application. Still, there is room for improvement. Compared to PC software, most of the mobile applications offer a limited number of features. Therefore, if you need to not only combine PDFs but also to convert other digital formats into PDF, edit, and merge documents, you’ll have to switch to a computer, install PDF software program, or take advantage of other web solutions such as the ones we’re about to show you.

How to Combine PDF Online?

If you want to organize your data and PDFs into one PDF document, you can also do it via web-based applications and avoid spending time on installations and updates, and space on your computer. As long as you have an internet connection, this is a great method.

Here are some of the best PDF tools for combining files online according to user feedback. Scroll down to find the optimal solution for your needs.

Combine PDF

Combine PDF— the name speaks for itself. You can use it to combine PDF documents and images (BMP, GIF, HEIC, HEIF, JP2, JPEG, JPG, PNG, PSD, TIF, TIFF, XCF.) in a literally just a few clicks.

  1. Drag and drop your PDF files and images or click the Upload Files button to select files and upload them.
  2. Click the Combine button and watch as the files are immediately merged and downloaded.

PDF Merge

PDF Merge, powered by Soda PDF, is a tool similar to Combine PDF. The steps for combining PDFs into one file are almost the same.

  2. Click on the Merge button and your document will be ready in 10 seconds.
  3. You can not only view but also edit the document directly in your browser before you save and download the new document.

As you will notice, there is a slight difference between these two web-based apps. In PDF Merge, you cannot drag and drop files. Instead, you have to upload each file separately, which can be inconvenient. Also, this app works only with PDF files; Doc files or images can’t be combined.

The upside of this web solution is the ability to make basic edits in the browser prior to download.

Sejda

Sejda is another web-based program that provides a PDF and image combining function. The advantage of this program lies in some of the additional settings it offers. For example, you have options such as ‘Include only specific page ranges,’  ‘Double-sided printing,’ and ‘Make all pages same size.’

To combine PDF files and images with Sejda, just follow these steps:

  1. Drag and drop files onto the page or upload them from OneDrive, DropBox, Google Drive or from the URL of the file.
  2. Click Merge PDF or More Options to optimize the document prior to merging.
  3. When all of the files have loaded and settings are as you want them, just click Merge Files.
  4. Now you have the option to save your document in a cloud storage site, download it, or share it via email.
