- Scenario
- Viewing and reading PDF documents on a mobile device where a specific background color is desired for better eye comfort.

Use Adobe Acrobat DC Desktop App to Edit Background
Since the mobile app does not support custom background colors, you can use the desktop version of Adobe Acrobat DC to permanently alter the document's background.
This method changes the actual background of the PDF file. Once the file is saved on your desktop, you can transfer it back to your mobile device to view it with the new color applied.
Launch Adobe Acrobat DC on your computer and open the target PDF file.
Click on the 'Edit PDF' tool located in the right-hand pane.
In the editing toolbar at the top, click on 'More', select 'Background', and then choose 'Add'.
In the Add Background dialog box, select your preferred custom color from the 'From color' palette and click 'OK'.
Save the modified PDF file and send it back to your mobile device for comfortable viewing.

Enable Night Mode on Adobe Mobile
If you just need a darker background for reading in low-light conditions, you can utilize the app's built-in Night Mode.
Submit a Feature Request to Adobe
You can officially suggest adding custom viewing backgrounds to the mobile app by submitting feedback directly to the Adobe development team.

Frequently Asked Questions
Does enabling Night Mode in Adobe Mobile change the actual PDF file?
No, Night Mode only temporarily inverts the colors on your screen to reduce glare in dark environments. The original PDF file remains completely unchanged when shared or opened on another device.
Can I permanently change the background color of a PDF on my phone?
Most mobile PDF readers, including Adobe Acrobat Reader, are designed for viewing and basic annotation. To permanently alter the document's background color, you generally need to use a fully-featured desktop PDF editor like Adobe Acrobat Pro DC or WPS Office Desktop.
Are there free alternative apps that support custom PDF reading backgrounds?
Yes, alternative mobile office suites like WPS Office offer specialized reading features, including Eye Protection and customizable background tints, completely free of charge. This allows for comfortable reading without needing to edit the file.
