- Product
- PDF Reader
- Device & OS
- not provided
- Scenario
- Opening and viewing a PDF document that displays incorrectly or feels divided.
- Observed behavior
- The PDF either shows two pages side-by-side instead of a single page, or the original document has been physically divided and extracted into separate files.
First, check your window tabs to determine if your PDF is simply displaying in a two-page layout within a single file, or if the actual document has been separated into multiple distinct PDF files. This will tell you if you need to change a view setting or combine files.
Change Page Display to Single Page View
If the document is a single file but displays two pages side by side, adjusting your reader's view settings will immediately resolve the issue.
Most PDF readers support multiple reading layouts. The side-by-side or 'Two Page View' is often used for reading digital books or magazines, but it can be distracting for standard documents.
Launch your PDF reader (such as Adobe Acrobat or Reader) and click on the 'View' tab located in the top menu bar.
Hover over the 'Page Display' option from the drop-down menu to reveal the available layout settings.
Click 'Single Page View' to disable the side-by-side layout and restore the normal one-page vertical scrolling view.
Combine Extracted or Divided PDF Pages
Use this method if your original PDF was physically split into multiple files or if specific pages were extracted.
Use WPS Office to Fix PDF Layouts and Merge Files
WPS PDF provides an intuitive interface to instantly switch between single and two-page viewing modes. It also includes powerful, built-in tools to merge, extract, and organize PDF pages efficiently.
- 1. Open the PDF in WPS Office: Launch WPS Office and open your affected PDF document.
- 2. Adjust the View Layout: Navigate to the 'View' tab on the top ribbon and simply click 'Single Page' to fix any unwanted side-by-side display issues.
- 3. Merge Split Documents: If the file was physically split, go to the 'Page' tab, select 'Merge PDF', and add your separated files to combine them back into one.

Frequently Asked Questions
Why did my PDF suddenly change to a side-by-side view?
This typically happens if a keyboard shortcut was accidentally triggered, or if the default zoom and layout settings in your PDF reader were altered to 'Two Page View' or 'Two-Up' display.
How do I know if my PDF is displaying two pages or if it was actually split into two files?
Look at the top of your PDF reader's window. If you see two separate file tabs or separate window instances, the document was split into separate files. If it is a single file tab showing two pages at once, it is just a layout setting.
Can I merge a split PDF without paying for a premium editor?
Yes, many modern office suites, such as WPS Office, include free built-in PDF tools that allow you to merge multiple PDF files into a single document without requiring a premium Adobe Acrobat subscription.
