- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- iOS and Android
- Scenario
- Reading and navigating PDF documents on smartphones or tablets with visual or auditory accessibility requirements.
- Observed behavior
- The user aims to configure and enable app-specific settings like Night Mode, alongside native OS tools like VoiceOver or TalkBack, for easier mobile PDF viewing.
Ensure your iOS or Android device software is updated to the latest version, as Acrobat Reader relies on native operating system accessibility tools for features like spoken feedback and global color inversion.
Enable Night Mode in Adobe Acrobat Reader
Use the built-in Night Mode to invert text and background colors within the app, significantly reducing eye strain in low-light environments.
Acrobat Reader includes a native Night Mode feature that instantly switches the document's bright white background to dark gray or black, while adjusting the text color to white or light gray. This is highly recommended for users with light sensitivity.
Launch the Adobe Acrobat Reader app on your mobile device and open the PDF file you wish to read.
Tap the screen once to bring up the top menu bar, then tap the 'View Settings' icon (often represented by a page display icon).
Locate the 'Night Mode' switch in the menu and toggle it on. The document will immediately adapt to a dark color scheme.

Configure iOS Accessibility Features (VoiceOver & Display)
Leverage Apple's native VoiceOver screen reader and display accommodations to navigate and read PDFs aloud on an iPhone or iPad.
Enable TalkBack and Display Scaling on Android
Use Android's built-in TalkBack screen reader and global display settings for accessible PDF reading on Android devices.
Read PDFs Easily with WPS Office's Mobile Features
WPS Office provides a highly accessible mobile PDF reading experience out of the box. With built-in features like Mobile View (Text Reflow), Night Mode, and Audio Reading, you can comfortably read documents on any mobile screen without relying entirely on complex system settings.
- 1. Download and Install WPS Office: Install the free WPS Office app from the App Store or Google Play Store and open it.

- 3. Enable Dark/Eye Protection Mode: Tap 'Tools', navigate to the 'View' tab, and select 'Night Mode' or 'Eye Protection Mode' for high contrast and reduced blue light.
- 4. Use Audio Reading: In the 'Tools' menu under the 'View' tab, tap 'Audio Reading' to have WPS Office accurately read the PDF text aloud to you.

Frequently Asked Questions
Does Adobe Acrobat Reader Mobile have a built-in text-to-speech feature?
Acrobat Reader Mobile primarily relies on your device's native screen readers, such as VoiceOver on iOS and TalkBack on Android. However, using the app's Liquid Mode feature can greatly enhance document structure, making it much easier for these system accessibility tools to read the text in the correct order.
How do I make the text larger in Adobe Acrobat Reader on my phone?
You can increase the text size by tapping the 'Liquid Mode' (water drop) icon at the top of the app. This feature reflows the document to fit your screen natively, allowing you to tap the text settings icon to adjust font size, character spacing, and line spacing directly.
Why is VoiceOver or TalkBack not reading my PDF correctly?
If your PDF is a scanned image without a recognizable text layer, screen readers will not be able to read the content. You will need to process the document with an Optical Character Recognition (OCR) tool first to convert the image into readable text.
Can I customize the background color of PDFs in Acrobat Mobile?
Apart from Night Mode, which provides a dark background, Acrobat Mobile does not offer extensive background color customization natively. For custom color filters (like sepia or high contrast), you can use your device's native OS accessibility settings, such as 'Color Filters' in iOS or 'Color Correction' in Android.
