Top 4 Ways To Merge PDF Online

Today we're going to look at how you can merge PDF online. There are lots of browser-based tools that can help you merge PDFs, but it can be hard to choose the best option, so we've put together a quick guide to help you out. We'll look at 3 easy tools to combine PDF online. Be sure to hang around until the end to find out about the best way to merge PDFs.

Part 1: How To Merge PDFs Online - Choose From 3 Methods

Browser-based PDF tools are certainly convenient, and they're usually a fast, easy way to combine PDF online. There are some downsides though, which we'll look at briefly before jumping in to look at the tools:

  • Privacy and security: any time you're using an online tool you are uploading potentially sensitive information to the internet, and it's not always easy to find out about the security features of any given tool.
  • Limited file sizes: most of these tools can only cope with PDFs up to a certain size. That's fine if you're just working with a few pages, but if you've got larger documents that need merging, online tools probably aren't up to the task.
  • Limited features: maybe you simply need to join two PDFs together, in which case you're probably fine. But if you want to insert one PDF into the middle of another, or carry out batch processes, you'll want to look for a more robust tool.

If you've realized that you need more than the free online tools can give you, you might want to jump straight to UPDF.

UPDF is software that contains a full range of tools for working with PDFs. Use it to merge PDFs effectively. It can insert a single PDF into multiple other files with its batch insert feature, allowing you to update a range of documents quickly and easily - great for updating contact information, for example. Besides, UPDF also supports merging or combining multiple PDFs into a single file within a few clicks. UPDF also makes it easy to reorder pages in any PDF or to combine multiple PDFs into one file.

It's simple to download, and UPDF is so easy to use that you'll be merging PDFs in no time, almost as fast as those clunky online tools you've tried before.

Merge PDF online free with these tools

If you're sure you want to stick with an online tool for your PDF-merging tasks, then you'll find something here that fits the bill.

Here's everything you need to merge several PDFs online in one PDF. We've checked out three popular online tools and listed the steps to save you time figuring them out for yourself.

1. iLovePDF

You might well have heard of this one before, it's one of the more popular online PDF tools. We've got a detailed article about iLovePDF merging that you can look at, and we've also summarized the basics of using it to merge PDF online free, right here:

  • Open iLovePDF in your browser and select 'Merge PDFs' from the top menu.
  • Drag and drop the files you want to merge into iLovePDF or click 'Select PDF files' to search for them.
  • Click 'Merge PDF' and wait for confirmation that the process is complete.
  • Download the newly-merged PDF file.

2. Smallpdf

Again, we've detailed the basic steps below, or you can take a look at our in-depth review of Smallpdf's merging tool if you prefer.

  • Open Smallpdf and select 'Merge PDF' from the Tools menu.
  • Use the 'Choose Files' button to select your files, or simply drag and drop them into the tool.
  • You can drag the files around to reorder them as you wish.
  • Click 'Finish' and then download the new file.

Smallpdf works fine if you only require occasional use. The free version limits you to creating two merged documents per day, after which you'll see a pop-up inviting you to upgrade to the paid version.

If you're looking for more functionality, UPDF is the way to go. Click below to give it a try.

3. Adobe Acrobat online tool

Lastly, let's look at Adobe Acrobat's online tool. Adobe is one of the bigger players in the PDF space, so you've probably encountered them before. You might not know, though, that they have a free online version that allows you to merge PDF online.

  • Open the Adobe Acrobat online tool.
  • Scroll down and choose 'Merge PDF' from the list of editing tools at the bottom.
  • Use the 'Select Files' button to locate and upload the required files, or drag and drop them into the tool.
  • Click 'Merge' and wait for the files to be combined.
  • Now, download the merged file.

Part 2: Merge PDF Online the Safe and Secure Way

As we've seen, online tools raise concerns about security and privacy and often come with restrictions around file size or number of processes per day.

Of course, nothing is stopping you from getting through that stack of ten merging tasks by tackling two each day until they're done. You're probably keen to just get it sorted though, no one wants that kind of admin task lurking on their to-do list for the whole work week.

This is where UPDF comes in.

Why is UPDF the best way to merge PDFs?

  • It lets you merge two PDFs and reorder all the pages. Want to insert a page with your company's new URL into the back matter of another PDF? No problem. Want to add the Chinese translation into an instruction book so that Chinese and English pages alternate? UPDF can do that too.
  • You can use it to merge 100+ PDFs into a single, continuous document using the Batch Combine feature. This is how you'd sort that instruction book if you wanted seven different languages combined into a single booklet.
  • UPDF can merge a PDF into several different PDFs at once with the Batch Insert tool. If you need to update all the literature for your dental practice to contain new staffing details and photos, this is the perfect way to do it.
  • It works across all your devices. With UPDF you can merge files just as easily on iOS as you can on Windows and Mac. That kind of flexibility simply can't be beaten.
