Fix Scanned PDF Changing to Landscape When Combining in Acrobat
Question details
A scanned portrait PDF automatically changes to landscape and clips content at the bottom when combined with other files.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Combining multiple PDF files using an online Acrobat subscription.
- Observed behavior
- The page orientation changes to landscape automatically during the merge process, which cuts off or clips content at the bottom of the original portrait page.
Ensure you have a reliable PDF viewer with a virtual 'Print to PDF' printer installed on your computer, such as Adobe Acrobat Reader or WPS Office.
Print to PDF to Lock Page Orientation
Use the 'Print to PDF' function to create a new, flattened version of the scanned document that permanently locks the correct orientation before merging.
By 'printing' the document as a new PDF file, you strip away problematic metadata that causes Acrobat's online merger to automatically rotate the file. This ensures the portrait or landscape layout remains exactly as you intend it.
Launch Adobe Acrobat Reader and open the specific scanned PDF file that is experiencing the orientation issue.
Go to the 'File' menu in the top left corner and select 'Print', or use the keyboard shortcut Ctrl + P (Windows) or Cmd + P (Mac).
In the Printer drop-down menu, choose 'Microsoft Print to PDF', 'Adobe PDF', or 'WPS PDF'.
Under the Page Sizing & Handling or Orientation section, uncheck any 'Auto portrait/landscape' options. Select 'Landscape' (or the orientation that correctly frames the preview without clipping the bottom content).
Click 'Print'. A dialog box will prompt you to save the file. Choose a new destination and file name, then use this newly created PDF when combining your files online.
Combine PDFs Without Orientation Errors using WPS Office
Bypass online merging bugs entirely with WPS Office. Its built-in PDF toolkit allows you to merge documents offline locally, preserving the exact layout, margins, and original orientations of your scanned pages without unexpected clipping.
- 1. Open WPS Office: Launch the WPS Office application on your computer and navigate to the 'PDF' tab on the home screen.
- 2. Select Merge PDF: Click on the 'Merge PDF' tool located in the main PDF workspace or under the 'Tools' menu.
- 3. Add Your Documents: Click 'Add Files' to import the scanned PDFs and any other documents you wish to combine into a single file.
- 4. Merge the Files: Arrange the pages in your desired sequence and click the 'Merge' button to generate the final PDF with perfect formatting.
Frequently Asked Questions
Why does Acrobat automatically change my scanned PDF to landscape?
Acrobat's automatic rotation feature often attempts to align pages based on text direction or document dimensions. In scanned documents, irregular margins or horizontal text artifacts can trick the software into forcing a landscape orientation during a merge.
Will printing to PDF reduce the quality of my scanned document?
Printing to PDF can apply slight compression. To avoid blurriness, ensure that your printer properties are set to 'High Quality' or 'Standard' rather than 'Minimum Size' before saving the new PDF.
How can I stop my PDF content from clipping at the bottom?
Clipping occurs when the aspect ratio changes during rotation. By unchecking 'Fit to page' and manually defining the orientation (Portrait or Landscape) in the print dialog prior to merging, you preserve the original dimensions and prevent the bottom content from being cut off.
