Enable the Built-in Night Mode in Acrobat Reader
Use Adobe Acrobat's native feature to invert the document's background and text colors.
Adobe Acrobat Reader offers a built-in Night Mode that specifically targets the document pane. This feature is excellent for darkening the page background and lightening the text to reduce glare without affecting the operating system.
Launch the Adobe Acrobat Reader app on your iPhone or iPad and open the PDF document you wish to read.
Tap the View Settings icon (usually represented by a page or display icon) in the top toolbar.
Locate the 'Night Mode' switch in the dropdown menu and turn it on to immediately invert the document colors.

Apply iOS Smart Invert for a System-Wide Dark Interface
Use the iOS Smart Invert accessibility feature to darken the entire app interface along with the document.
Configure Accessibility Shortcuts for Grayscale Viewing
Create an iOS shortcut to quickly toggle Smart Invert and combine it with Acrobat's Night Mode for a grayscale reading experience.
Enjoy Seamless Night Mode Reading with WPS Office
If you want an easier way to read PDFs in low-light environments, WPS Office for iOS provides a highly optimized Dark Mode. It seamlessly adapts the entire user interface and the document background to protect your eyes, without requiring complicated system-wide accessibility workarounds.
- 1. Install and open WPS Office: Download WPS Office from the App Store, open the app, and select the PDF document you want to read.
- 2. Open the Tools menu: Tap the 'Tools' icon located at the bottom left of the screen to reveal the document options.
- 3. Enable Dark Mode: Navigate to the 'View' tab and select 'Dark Mode' or 'Eye Protection Mode' to instantly switch the app and document to a comfortable low-light theme.

Frequently Asked Questions
Does Acrobat Reader's Night Mode alter the colors of images inside the PDF?
Acrobat's built-in Night Mode primarily inverts text and background colors to reduce glare. However, depending on how the PDF was created, some images or graphics might also experience color inversion. Using iOS Smart Invert generally does a better job of preserving original media colors.
Why are the menus still bright white when Night Mode is turned on?
The native Night Mode in the Adobe Acrobat app is designed strictly for the document viewing pane. To achieve a completely dark interface, including toolbars and menus, you need to utilize the iOS Smart Invert feature or the iOS system-wide Dark Mode.
How do I turn off Night Mode in Adobe Acrobat Reader?
To disable Night Mode, simply tap the View Settings icon on the top toolbar while your PDF is open, and toggle the 'Night Mode' switch back to the off position. The document will return to its original light background.
Can I read PDFs in true grayscale on my iPad?
Yes. By enabling both Adobe Acrobat Reader's built-in Night Mode and the iOS Smart Invert feature at the same time, the overlapping color inversions result in a grayscale display for your PDF content.
