Why would I need to combine files?

A typical case sounds something like this: several professional colleagues are working on a group project, and they’ve all done work separately in PDF format. Now they want to combine their files into one report.

However, they don’t know how to combine or merge their respective PDF documents. They hit the internet looking for PDF tips and suggestions on how to combine their files into one combined PDF document.

So what is the top reason who you can’t combine PDF files into one single PDF document?

The PDF is Secured

PDF files can be combined either secured or unsecured. A secured PDF file means that it is protected with a password. If you want to combine multiple secured PDF files, the process is a bit tricky.

Want to secure your PDF documents? Try Soda PDF’s online tool to Password Protect PDF.

How to merge unsecured PDF files with Soda PDF

  1. Open your software or visit the Soda PDF website and look at the main navigation menu.
  2. Click on the Tools menu and select Merge PDF.
  3. Click the button to add the files you want to merge in your PDF – you can also drag and drop files or or reorder each page.
  4. Click on the Merge Files button
  5. Finally, click on the Save button

Note that if your total file size exceeds 2 GB, the process will not work in popular professional apps like Adobe Acrobat. You can get around this by first compressing your individual PDF files in order to make them take up less space. After that, you can go ahead and combine files. Hopefully, you’ll end up with a PDF file that’s less than 2 GB.

How to merge secured PDF files in Adobe Acrobat

If your PDF files are secured, you’ll need to know their passwords. If you try to combine files which are secured (password protected) in Adobe Acrobat for example, you will be asked for the permission password when you click on the Combine PDF files button.

Otherwise, the process is the same in Adobe Acrobat as for unsecured PDF files. You can use the desktop version to combine files easily. If you don’t enter a password when prompted, you won’t be able to complete the PDF merging process and you will get an error message. In this case, if you don’t have the password, even Adobe Acrobat won’t work to combine files. This is where third-party software to combine multiple PDF documents comes into play.

If you’re having trouble merging protected (secured) PDF documents, you might want to remove the security you combine files into one. If you don’t know the password, however, you need to find a way to decrypt the file before you combine files.

With special software, you can simply remove the security from the PDF documents without needing to enter the password. If you simply add the secured files, the software will decrypt them before allowing you to combine files. It will then create a new password-free combined file.

Such applications are designed to remove restrictions on edit, printing, copying, and such from your PDF files. In some cases, if the file is secured with a password, you’ll be asked to enter it, and once you do, the file will become unsecured and password-free. You can also try using Soda PDF’s Unlock PDF online tool to try and open a password-protected PDF.

Note that you can run Soda PDF Desktop on any Windows machine and combine files with ease. If you’re a MAC user, we recommend using Soda PDF Online instead.

Remember that Adobe Acrobat is unable to combine PDF files if the total file size is larger than 2 GB. To overcome this limit, we suggest using tools like Soda PDF in order to merge or split your PDF files. Soda PDF has an Online or Desktop app, both of which are easy to use for combining multiple files into one.

If you have removed security restrictions from your files, you’ll be able to easily combine or split your PDF files using an online tool like Soda PDF. You’ll also enjoy no limits on your document sizes when performing the merge function.

Remember that with an online tool like Soda PDF, you can perform multiple functions related to your PDF files, such as split, merge, edit, save and more – all in one place, and in your browser window. If you prefer, you could download the desktop version of Soda PDF as well.
