Drop Your Files Here Unlike traditional DOC files — such as those you create with Microsoft Word or Google Docs — a PDF looks the same on any system. This is because DOC files pull information from the system on which it's opened, such as installed fonts and other operating system-specific details. PDFs, however, are more akin to images, so they always look the same. This versatility makes PDFs perfect for sharing documents on the internet! However, they also are more difficult to edit and can be tricky to work with, so there are trade-offs. Why would you need to combine PDFs? If you have a DOC file and you want to add parts of another DOC file to it, the process is simple: just cut-and-paste everything from one to the other. With a PDF, it's not so simple. Unless you have PDF editing software, you can't add a new page. It's also tricky to copy text from one PDF to another, especially if one PDF is a scan of physical paper. Thankfully, we can combine a PDF for you for free without any additional software!

How to combine PDF files for free? Our tool above can combine two or even up to 20 PDFs for you. This is an easy way to bring multiple PDFs together into one. To start, upload up to 20 PDFs. Conversely, you can drag and drop your PDFs to the drop area. Once you've uploaded all your files, make sure they are in the correct order. Our tool will put the first PDF at the top of the new PDF, the second one underneath that one, and so on in that order. You can drag and drop your files in the queue to make sure they are right. When everything looks good, combine them. Our system will combine all the PDFs into one PDF and start the download for you. Do you want to combine more than 20 PDFs? You can do that too! Combine your first 20 PDFs using the steps we just discussed. Then, upload that combined PDF you just made along with the rest of the PDFs you want to add. Combine again to get a new, even longer PDF. You can do this as many times as you need! One thing to remember, though, is that you must download your combined PDFs within one hour. If you do not, you'll need to re-upload your files and try again.
