MERGE PDF
Merge PDF files without installing any software. Simple, quick, reliable PDF combiner.

Combine PDFs In Just One Click
Do you have multiple PDFs that you’d like to join as a single file? Then you've come to the right place. This online tool lets you merge PDF files to save them as a single file on your computer or mobile. You don’t have to register, it’s free, and the tool is really easy to use.
Once you download the file, remember that you can compress, sort, and even edit it with FormatPDF’s complete suite of tools.



100% Online: Merge PDFs Without Installing Programs
One advantage of our service is that you don't need to install any programs. As such, you can merge PDFs online anywhere at any time, whether from your computer —on a web browser, like Chrome, Edge, or Firefox — or your mobile or tablet.

Totally Secure And Private
With our combiner, your files won’t be publicly displayed anywhere. Thus, only you will be able to see and alter the documents you upload. Also, you're the only one who can download the resulting file, and no one else will have access to it. Your privacy is very important to us. See our policy on this.

No Advertising When You Merge PDF Documents
In the past, you might have found software that promised to combine PDFs but, once you downloaded the resulting file, there was a watermark on every page. By comparison, rest assured that our merger tool is developed to merge files without adding a watermark or any other advertising.

Compatible With All Devices Without Installation
Another of the advantages of our PDF merger is that it’s compatible with all devices and operating systems. This ranges from Windows to Android, going through Mac, Linux, iOS, and any other platform. So you can use it, whatever device you’re on.

Save Space On Your Device With Our Cloud-Based Tool
A further advantage of merging PDFs online with this tool is that the whole process takes place in the cloud. Thus, you don't need to take up hard disk memory or computing resources on your device while combing PDF files. The only thing you have to do is download the resulting document when it’s ready.

Joining PDFs Has Never Been Easier
Forget about the complex processes to combine PDFs that you may have encountered in the past. As this is a 100% online PDF combiner, the only thing you need is your internet browser. The merging process takes just a few seconds, resulting in a single convenient document to download, easy-peasy.
Step By Step: How To Merge PDF Files
Here are the steps to merge your PDFs with our tool:
- To upload the documents you want to merge, select all of them (ctrl + click on Windows; cmd + click on Mac), and drag them to the action space above. If you prefer, you can also click on the "Select PDF files" button and upload the documents from the file explorer.
- Organize the files in your preferred order, and click on the "Merge PDF" button.
- In a few moments, your browser will automatically download the resulting file. If not, you can download it manually by clicking on the "Download PDF" button.
Other Options To Combine PDFs
Merge PDFs On Windows
