PDF documents are the most common format used when sharing or working on digital documents. Most of us feel that the PDF format is not editable or changeable. However, there are many tools available in the market that allow users to make changes to their PDF documents both Online & Offline. If your PDF files are private and contain confidential information, then it would be risky to upload them over the internet.
Instead, you could use an offline tool that can perform all the PDF editing and management tasks on your PC without the need to upload the files to any server. This article focuses on how to combine PDF files offline in different ways.

Method 2 – Using MS Word
Using the MS Word program is not a recommended option to combine PDF files. But in case you do not have the above-mentioned apps, then MS Word can function as an offline PDF merge tool. However, we cannot guarantee the quality of the content because forcibly opening a PDF into MS Word does reduce the quality of the content and can cause loss of formatting in some cases. Here is what you need to do to merge multiple PDF files offline.
- Launch the MS Word app and click on the Open option.

- Locate the PDF files you wish to merge and select all of them.
- A prompt box will appear stating the conversion of the PDF to Word document format. Click on OK.

- All the PDFs will now be converted to Word format and open in different MS Word Windows.
- Navigate to the first document and press Ctrl + End keys to reach the end of the document.

- Now go to the next document that you wish to merge, press Ctrl + A to select all the content, press Ctrl+ C to copy the content, and finally move to the first document and press Ctrl + V.
- All the content of the second document will be pasted at the end of the first document.
- Press Ctrl + End again on the first document to move the cursor to the end of the content and repeat the above steps with the third document.
- This way you can select, copy and paste all the content in the first document.
Note – The PDF to Word Document conversion process may lead to loss of formatting and structure of the document.
- Check and review the entire content and make changes if required.
- After all the content has been pasted, press the File button in the top left corner and select Export.
