How to Combine Multiple Open PDFs into One Document
Question details
The user wants to combine several currently open PDF documents into one single file without needing to manually locate each file within its respective storage folder.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Merging multiple PDF files that are already actively open in the application workspace from various folder locations.
- Observed behavior
- The user has multiple files open and requires a streamlined feature to merge them directly from the workspace instead of re-importing them from the file explorer.
Ensure all the PDF files you intend to combine are currently open in your Acrobat workspace, and save any pending edits in the individual documents before initiating the merge.
Combine Open PDFs Using Adobe Acrobat
Use the built-in 'Add Open Files' function in Acrobat to quickly compile active documents into a single PDF.
Adobe Acrobat includes a dedicated feature for merging files that are actively open. This bypasses the need to browse your computer's directories, saving significant time when compiling reports, invoices, or research documents.
In Adobe Acrobat, navigate to the top menu and select 'File', then hover over 'Create' and click on 'Combine Files into a Single PDF'.
In the Combine Files window, click on the 'Add Files' dropdown menu located at the top left, and choose the 'Add Open Files' option.
A dialog box will appear displaying all PDFs currently open in Acrobat. Check the boxes next to the files you wish to merge, arrange them by dragging the thumbnails into your preferred order, and click 'Combine'.

Frequently Asked Questions
Can I arrange the order of the open PDFs before they are combined?
Yes. After selecting 'Add Open Files', you can drag and drop the file thumbnails in the Combine Files preview window to organize them into your desired sequence before finalizing the merge.
Will combining the open PDFs delete or alter my original files?
No, merging PDFs creates a completely new, independent document. Your original open files remain untouched and safely stored in their original folder locations.
Why is the 'Add Open Files' option greyed out or missing?
This usually occurs if the PDFs are open in a different application (like a web browser or third-party reader) rather than natively within Acrobat, or if the open documents have security restrictions that prevent content extraction and merging.
Can I select only specific pages from an open PDF to include in the combined file?
Yes. In the Combine Files window, you can double-click a file's thumbnail or click the expand icon to reveal its individual pages. From there, you can select only the pages you want to keep or delete the ones you do not need before clicking 'Combine'.
