How to Set a PDF to Open at 125% Zoom in PDF-XChange
Question details
The user needs to configure a PDF document so that it automatically opens at a specific 125% magnification level for clients.

- Product
- PDF-XChange
- Device & OS
- not provided
- Scenario
- Preparing and saving a PDF document with explicit viewing preferences before distributing it to end-users or clients.
- Observed behavior
- Modifying the page size or orientation does not automatically dictate the default zoom level, requiring the user to explicitly configure the document's initial view settings.
Ensure you are using a version of PDF-XChange that supports editing document properties (such as PDF-XChange Editor), as basic free readers often lack the capability to save initial view metadata.
Configure the Initial View Settings in Document Properties
Use the document properties menu in PDF-XChange to force the PDF to open at your desired 125% magnification level.
PDF formats support an 'Initial View' property that instructs compliant PDF viewers on how to display the document upon opening. By setting this property, you can dictate the exact zoom percentage, bypassing standard default views.
Launch PDF-XChange Editor and open your target PDF file. Press 'Ctrl + D' on your keyboard, or navigate to 'File' > 'Document Properties'.
In the Document Properties window, select the 'Initial View' category from the left-hand menu pane.
Locate the 'Magnification' or 'Zoom' dropdown menu within the Initial View settings. Type in '125%' or select it from the available options.
Click 'OK' to apply the settings, then save the document (Ctrl + S) to embed the new initial view preferences into the file.

Effortlessly Manage PDF Views and Edits with WPS Office
WPS Office features a robust built-in PDF tool that makes reading, annotating, and adjusting the view of your PDF documents incredibly smooth. It handles standard PDF formats seamlessly, providing an all-in-one workspace.
- 1. Open WPS Office: Launch the WPS Office application and click on 'Open' to select your PDF document.
- 2. Navigate to the View Tab: Look at the top ribbon menu and click on the 'View' tab to access various reading and display configurations.
- 3. Adjust the Zoom Level: Click on the 'Zoom' tool and select or manually enter '125%' to scale the document text and images to your preferred size.

Frequently Asked Questions
Why does the PDF ignore my 125% zoom setting when sent to clients?
Many modern PDF viewers, especially those built into web browsers, are programmed to override a document's initial view settings in favor of the user's default application settings, such as 'Fit to Width' or 'Automatic Zoom'.
How do I change the default zoom level for reading all PDFs on my device?
In your PDF viewer's preferences (usually found under Edit > Preferences or Settings), navigate to the 'Page Display' or 'View' section. From there, you can set a global default custom zoom percentage that applies to any PDF lacking a specific initial view setting.
Does changing the document page size automatically change the zoom?
No. Modifying the physical page size or orientation only alters the document's layout dimensions. The magnification or zoom level used upon opening is an entirely separate setting that must be explicitly configured.
