Adjust the File Type Filter in Acrobat

Change the file picker settings in Acrobat to display all supported formats instead of filtering exclusively for PDFs.

By default, the Adobe Acrobat file selection window might be set to only look for existing PDF files. Adjusting the drop-down menu allows you to view and select Microsoft Office documents.

1
Open the combine files tool

Launch Adobe Acrobat DC and select the 'Combine Files' or 'Create PDF' option from the main tools menu.

2
Open the file selection window

Click on the 'Add Files' button to open the standard file explorer prompt.

3
Locate the file format drop-down

Look at the bottom right of the file selection window, next to the 'File name' input box, and find the file type drop-down menu.

4
Change to all formats

Click the drop-down menu and change it from 'Adobe PDF Files (*.pdf)' to 'All Supported Formats' or 'All Files (*.*)'.

5
Select your Office files

Your Word, Excel, and PowerPoint files will now be visible. Select the files you wish to convert and proceed.

Adjust the File Type Filter in Acrobat
File Visibility Restored: Once 'All Supported Formats' is selected, Acrobat will remember this preference for your current session, making it easier to add multiple Office files.

Frequently Asked Questions

Do I need to keep Microsoft Word open while Acrobat converts the file?

No, you do not need to have Microsoft Office applications actively running. However, the desktop versions of these applications must be installed on your local system for Acrobat to utilize their conversion processes.

Why does Acrobat say it cannot open my Word document after I select it?

This usually happens if Acrobat lacks the necessary file permissions, the file is corrupted, or if Microsoft Office is not properly installed locally. Repairing your Microsoft Office installation often resolves this integration error.

Can I combine files into a PDF if I only use Office 365 online?

Adobe Acrobat cannot directly convert files from online-only Office applications. You must download the documents to your local hard drive and use a compatible local desktop application to process the conversion.

What should I do if the 'All Supported Formats' option is missing?

Ensure you are using Adobe Acrobat DC, not the free Adobe Acrobat Reader, as Reader has limited file creation capabilities. If you are using the correct version, try updating the software to the latest patch.
