Working with PDFs has become a daily reality for most of us in the digital age. We regularly need to edit, scan, or merge PDF documents. Without the right software, this process can become tedious and frustrating.
That’s why it’s essential to do your research on the best PDF software tools out there. This article will focus on 24 of the best PDF merger tools that cater to your specific needs. This software allows you to take multiple PDF files and combine them into a single file.
So, whether you require a PDF merger tool with cloud connectivity, free or paid options, software that enables data privacy and security, or tools you can use offline, we’ll cover the ins and outs of several software options so you can make an informed decision.
Let’s get started!
What Is PDF Merging?
As we’ve mentioned, PDF merging software enables you to collate information from multiple PDFs into a single PDF file. This saves time since you don’t need to navigate between several PDFs to access your needed information. You can also share information more effectively without the risk of confusing your colleagues with numerous PDFs they must sort through to find the relevant content.
For example, let’s say you need to send a batch of reports to someone. By merging all of the PDF files into a single PDF document, you guarantee that the recipient will have all the information and won’t accidentally overlook one of the reports. This is helpful when you’re making a free fundraising guide or an employee playbook where you need to share a lot of information at once.
But to do this, you need PDF merger tools, and that’s where we come in. We will help you choose the right one by covering 20 of the best tools out there. We have assessed each option based on its features, cost, and speed.
In addition, we have categorized them according to specific needs, so you can easily browse through this article to locate the software that fits your context.
Best For Cloud Connectivity
Remote working is quickly becoming the norm in many industries. Since employees work on different devices throughout the day, it’s crucial to have a central location where everyone’s output can be safely stored and shared for collaboration. To avoid all the struggles and to maintain communication with employees, most companies are using the power of technology nowadays. That makes cloud connectivity important, so we’ll take you through the best options.
SodaPDF is a software program available on desktop for Windows and Mac, but you can also access it on the web. While both versions connect to Google Drive and Dropbox, you also have the option of saving files on the cloud, making it ideal for remote work.
This PDF merger software not only combines numerous PDF documents into one merged PDF document but also gives you the option of emailing the single PDF document directly from the software, combining with a good email finder to create an effective and relevant email list. You can even use it offline. Moreover, it is important to clean your email list regularly in order to avoid using invalid addresses.
However, the free version has limited features. For example, you won’t be able to convert files or reorder your PDF pages. It also doesn’t include PDF encryption which could compromise the safety of your documents.
So, if you are looking for advanced features, opt for the paid version, which offers editing options and batch processing, among others.
The paid version provides three different pricing plans:
- Standard – $8 per month for monthly billing or $6.75 per month for a yearly billing
- Pro – $12.50 per month for monthly billing or $10.50 per year for a yearly billing
- Business – $20 per month for each license or $16.75 per month for a yearly billing
Adobe Acrobat DC
Adobe Acrobat is packed with advanced features that make working with PDFs simple and seamless. Not only can you upload and share large files, but you can also edit documents using the rotate, extract, arrange, replace, and insert functions to create the perfect merged PDF file.
The user-friendly interface and ability to store all your work in the cloud make this one of the most popular PDF tools. You can even transfer files with a link and access the service on mobile, desktop, or the web, enabling effective team collaboration.
Another nifty feature is that you can merge different file types, so if you need to combine a Microsoft Office document and images, this won’t be a problem. Adobe Acrobat DC even offers security features to protect sensitive documents.
However, this software consumes a lot of resources which could slow things down. Adobe Acrobat DC is also pricier than other options.
- Standard – $14.12 per month
- Pro – $16.29 per month
Nitro PDF Pro
If you’re looking for a simple tool that’s streamlined and sparing on resources, then Nitro PDF Pro is for you. With its review, edit, sign-on, and mark-up features, you can alter your PDFs as you see fit and quickly merge files.
Make sure your work is always saved by integrating with Nitro Cloud, which makes for effective collaboration. This fast, user-friendly tool converts different file types, making the merging process easy.
Nitro PDF Pro is limited insofar as it doesn’t have a mobile app, and unfortunately, the desktop version isn’t compatible with Mac.
You can try it for free with their 14-day trial or purchase a one-time license at $179.99 per user.
Best Free Versions
ILovePDF is an excellent free option because it includes all the features you need to edit your PDFs painlessly. Plus, it’s compatible with Windows and Mac while also being web-based.
Compress, unlock, convert, merge, split or watermark your digital files in no time. You can even rearrange or rotate pages, while the thumbnail function makes it easy to keep track of and organize your documents.
You must upload your documents to the platform before you can start merging, but the drag-and-drop feature makes this simple. With a click of the merge button, you’re done. Connecting to Dropbox or Google Drive guarantees that all your work is saved.
The free version includes access to a selection of tools but only offers limited document processing of up to 25 files of 100MB in total. It also features ads which can be annoying.
The premium account gives you complete access to all the tools with unlimited batch processing. It also excludes ads and comes with customer support. This costs $4 per month, billed annually.
There is also a business account at a customized price.
Combine PDF is the perfect free PDF merging software if you work with a wide range of individual files that come in different file modes. This software can easily convert PNG, DOC, or JPEG formats to create a single PDF with all the necessary information. You can also rearrange the pages by dragging and dropping the file blocks.
While you are limited to combining up to 20 PDF or image files, you don’t need to install any software to use the service. Files are also deleted after an hour for added security, so make sure to download your PDF straight after it’s created.
Combine PDF may not have a wide selection of editing features, but its simple user interface makes it great for beginners who only need to merge a limited number of documents to create the output PDF file.
This PDF merging software works on desktop and is compatible with Linux, Mac, and Windows. What sets it apart from other tools is that you can merge an unlimited number of documents and use it as often as you like.
As for features, you can split, extract, rotate or reorder pages and use batch processing tools to manage multiple documents.
However, the basic version comes with limitations. You won’t be able to connect to cloud storage, and it doesn’t offer customer support. You also can’t email or share the merged PDF directly from the platform. Additionally, it doesn’t provide file conversion tools, so you will need another service for this.
Luckily, you can upgrade to PDFsam Enhanced for additional features. This enables you to convert, secure, sign, review, and edit PDFs. It also comes with OCR and costs $69 per user per year for the standard version.
PDFBinder delivers speed without compromising quality – even if you are working with large PDFs. Its key differentiator is the simplicity of the software, which makes it light on resources so your computer won’t get sluggish. You can also merge an unlimited number of documents without being interrupted by ads.
Additionally, your original file sizes are preserved, and you have the option of rearranging the page order. Users who are starting out enjoy the accessible interface that offers the drag-and-drop option.
On the other hand, you will have to go without rich editing features or a conversion tool. PDFBinder also doesn’t allow you to insert one PDF into another, and it only supports Windows.
If your primary goals are quality and PDF file size, DocuPub is good enough to get the job done. While it may not offer rich features, it merges documents fast because the software is simple and streamlined.
Another feature that makes it stand out is the option of uploading documents in various formats. Now you can easily combine a PowerPoint, Excel, or Word document. DocuPub also allows you to compress, rescale, or resize PDFs. So, if you have specific file requirements, you can change your PDFs accordingly.
You can even convert your files without installing anything – upload the document and select what you want to change it to. The simple interface is straightforward and provides clear instructions for using the platform.
The main limitation of DocuPub is that a single file cannot exceed 20 MB. So, if you are a beginner working with documents that are not exceptionally large, this PDF merger tool will do the trick.
If your favorite operating system is Mac, then you don’t need to worry about buying a PDF merger tool because Apple already has a free version. It’s pre-installed on your device, so you don’t need to download anything, and with it, you can annotate, sign, and merge PDFs.
While Apple Preview’s editing powers are somewhat limited, you will be able to combine and merge PDFs with ease. Plus, you can rotate, reorder, and remove pages. However, you won’t have access to an OCR tool, and you can’t edit PDF text.
If you only need to execute simple PDF functions, this tool will get the job done with minimal effort or investment.
