Turn 2 or more PDFs into 1 file

PDFs are pretty easy to create and are meant to be shared across the web. When creating one or more documents in the PDF format, it’s sometimes more convenient to consolidate PDFs into a single document. In this article, we’ll explain how to attach PDF files to one another so that you can make a single PDF file from multiple files. The act of connecting PDFs into a single document is generally called “merging” and is pretty easy to do with a third-party app. 

Is There an App to Merge PDF Files?

Yes, there’s an app that easily allows you to put multiple PDFs into a single file. The PDF.Live merge tool allows you to make a single PDF file by uploading multiple PDF files to the tool and merging them. PDF.Live’s tool is entirely web-based, which means no additional software or downloads are required to turn multiple PDFs into one. 

1. Head to PDF.Live’s PDF Merge tool

2. Click Select File to Merge. Or Drag and Drop your PDF into the tool. 

drop a PDF file to merge or select the green button and choose files from your computer

3. Once your first PDF is uploaded, you’ll see the option to upload a second PDF

You'll see the first uploaded PDF in the workspace. Click the plus character and add more PDFs.

4. Click Merge PDF to join all of your PDFs into a single document. 

After you select Merge PDF, you'll see the action icons that read Document Merging in Progress.

5. After a few seconds, your merged file will be available to download via the Download button. 

When your merged PDFs are ready, you'll see a message that says so. Click the download button.

Merging PDFs and Other Files

If you want to convert multiple files to the PDF format and merge them, a few extra steps are required before you use PDF.Live’s merge tool. 

You will need to turn all of your other files into PDFs before you can consolidate your PDFs into a single document. 

To do this, head over to the PDF.Live convert PDF page to see some popular file formats that you can convert to PDFs. For example, you can convert DOC, XLS, and PPT files to PDF documents. 

You cannot create one PDF from multiple files that are not PDFs. All of your files need to be PDFs before you can combine them.  

However, if you want to put all of your files in a single compressed file for sharing, consider the benefits of a Zip file. Zipping allows you to “smoosh” multiple file types together into a single format (.zip) for easy sharing. 

How to Add PDF Files Together

Adding two or more PDFs together is simple with PDF.Live’s merge tool. This tool will allow you to add as many PDFs as you want to create a single document. You can add a PDF to another PDF, or add multiple PDFs together. 

  1. Open PDF.Live.
  2. Create an account (name and email required).
  3. Upload your 1st PDF.
  4. When prompted, upload your 2nd, 3rd, etc., PDF.
  5. When all are uploaded, select merge.
  6. Wait patiently; it takes only a few seconds but larger files take longer.
  7. Download.

Misc FAQs About Merging PDFs

Can you merge PDFs of different sizes?

Yes, multiple PDFs of different sizes can be combined into a single PDF file. A PDF file can have landscape and portrait pages, as well as 8.5 x 11 standard paper size mixed with other custom sizes. You may run into issues when you print a PDF with varying page dimensions. If you’re set up to print to 8.5 x 11 paper, for example, all PDF pages default to be scaled to fit the 8.5 x 11 dimensions.

Is PDF.Live a PDF merge software that must be downloaded and installed?

No, PDF.Live is an online, web-based service that doesn’t require bulky software downloads to function. Simply head over to PDF.Live to view the merge PDF and many other tools for working with PDFs.
