Use Adobe Acrobat or Adobe PDF Pack to Combine Files

Adobe Acrobat (Standard or Pro) and the Adobe PDF Pack online service both support merging multiple scanned files into a single PDF document.

While the free Adobe Acrobat Reader allows you to view PDFs, it does not include the feature to merge files. You will need access to a premium Adobe product, such as Acrobat Pro, Acrobat Standard, or an active Adobe PDF Pack subscription.

1
Open the Combine Files Tool

Launch your desktop version of Adobe Acrobat or sign in to the Adobe PDF Pack online portal. Navigate to the 'Tools' menu and select the 'Combine Files' option.

2
Add Scanned Documents

Click the 'Add Files' button and select the scanned documents from your computer. You can also drag and drop the scanned image or PDF files directly into the workspace window.

3
Arrange the Pages

Drag the file thumbnails to reorder the scanned documents into your desired sequence. You can also hover over individual pages to delete any unwanted scans.

4
Create the Combined PDF

Click the 'Combine' or 'Merge' button at the top right corner. Acrobat will process and merge the scanned files. Once finished, navigate to 'File' > 'Save As' to store the new PDF.
