How to Merge PDF Files in SharePoint

Muhimbi’s PDF Editor for SharePoint lets you merge PDFs in SharePoint Online or on-premises.

Import PDF documents into your existing document and reorganize pages. Or, drag and drop to reorder pages, delete unnecessary pages, or add blank pages.

There are two ways to merge PDF files with SharePoint PDF Editor online:

  1. Import a PDF from your computer.

  2. Import a PDF from SharePoint.

Step 1: Opening PDF Files

Open PDFs in SharePoint

Go to the SharePoint library and click Upload to import a PDF from your computer or select an existing PDF from the library.

Click Open from the dropdown menu and choose Open in PSPDFKit Editor.

Alternatively, select a PDF from your SharePoint library and choose Edit with PSPDFKit Editor from the toolbar or by right-clicking on the PDF file.

Step 2: Combining PDF Files

Combine PDF files

In the top-right toolbar, next to the magnifying glass icon, click the dropdown arrow and select Document Editor. Then select Import Document to add a PDF from your computer. The PDF will be imported within the existing PDF in SharePoint. When you click Save as, the two PDFs will be merged into one and saved on your computer. If you don’t want to save a merged PDF in SharePoint Online, click Cancel in the bottom-left corner.

Alternatively, when you click Save, the added PDF will be merged into the existing one, and the next time you open a PDF, it’ll contain all the pages from the added document.

If you want to merge PDFs that are in SharePoint, it’s more convenient to choose the second option, which is also accessible through Document Editor. Click the three dots in the top-right corner and choose the Import from SharePoint option.

Select the PDF file you want to merge and click Open. The merged PDF document will automatically show up in PSPDFKit Editor.

Step 3: Viewing and Editing Merged PDFs

After merging PDF files in SharePoint, you can use Document Editor to move, copy, or delete pages and reorganize your document completely. Alternatively, you can use other PDF editing options available in our SharePoint PDF Editor, including content editing, annotations, redaction and more.
