How to Combine Multiple PDFs Into One

by Chris HoffmanUpdated September 28, 2017

Portable Document Format files can contain one or more pages. If you have several PDFs, you can combine them into a single PDF document. The combined document will contain the pages in the first document followed by the pages in the other PDF documents in the order you specify. Adobe’s commercial Adobe Acrobat Standard or Professional programs include built-in functionality for merging PDF documents. If you don’t have Adobe Acrobat, you can use a free Web-based or desktop application to combine PDF documents.

Open Adobe Acrobat, click the “Create PDF” button on the toolbar and select “From Multiple Files.” Click the “Browse” button in the window that appears, browse to PDF documents on your computer and double-click them to add them to the list. Drag and drop PDF documents up and down in the list to change their order and click the “OK” button to create your combined PDF file. Click “File” and select “Save As” to save the created PDF file to your computer.

Navigate to the Merge PDF website at in your Web browser. Click the “Browse” button on the page, browse to a PDF file on your computer and double-click it. Repeat this process to add multiple PDF files, then click the up and down arrow buttons to re-order the files. Click the “Merge PDF” button on the page and click “Download” to download your combined PDF file.

Download and install PDF Split and Merge from in your Web browser. Click “Start” after installing it, select “All Programs,” click the “PDF Split and Merge” folder and select the “PDFSam” shortcut. Click the “Merge/Extract” option in the program’s sidebar, click the “Add” button, click a PDF file on your computer and click “Open.” Repeat this process to add additional PDF files, then select a PDF file in the list and click the “Move Up” or “Move Down” buttons to re-order the PDF files. Click the “Browse” button in the Destination Output File section, type a file name for the merged PDF file, press “Enter” and click the “Run” button.


If you don’t see the “Create PDF” button on the toolbar in Adobe Acrobat, click the “View” menu, point to “Task Buttons” and select “Show All Task Buttons.”

Adobe Acrobat is a commercial program, distinct from the free Adobe Reader program. Unlike Adobe Acrobat, Adobe Reader can only view PDF files.
