- Device & OS
- not provided
- Scenario
- Opening and viewing an interactive, fillable PDF form on a mobile device.
- Observed behavior
- The interactive text fields automatically display a blue highlighting background that cannot be modified or hidden within the mobile application's settings.
Understand that the blue highlighting is an app-level usability feature designed to help mobile users locate fillable fields easily. It does not alter your original document design or affect the printed version of the PDF.
Adjust Form Field Settings on a Desktop PDF Reader
Since the mobile application restricts changes to form field backgrounds, you must use a desktop application to modify the display preferences.
The Acrobat Reader mobile app does not currently provide an option to hide or change the background color of form fields. Furthermore, this blue tint is an application-level overlay and is not caused by your InDesign export settings.
To properly adjust the form-field display appearance, you need to open the PDF in the desktop version of a PDF viewer, which offers comprehensive form-field settings.
Send the interactive PDF file from your mobile device to your Mac or Windows computer via email, cloud storage, or a direct file transfer.
Launch a desktop PDF reader such as Adobe Acrobat, Reader, or WPS Office, and open the transferred PDF document.
Navigate to the application's 'Preferences' or 'Form' settings. Look for the option labeled 'Show border hover color for fields' or 'Field highlight color' and disable or change it according to your preference.

Edit and Fill Interactive PDFs Seamlessly with WPS Office
Bypass mobile viewing limitations by using WPS Office's comprehensive PDF editor. WPS Office allows you to easily view, fill, and manage interactive PDF forms on both desktop and mobile platforms with advanced customization.
- 1. Download WPS Office: Install WPS Office on your desktop or mobile device directly from the official WPS website or your device's app store.
- 2. Open the PDF Form: Launch WPS PDF and browse your files to open the interactive PDF form you need to edit.
- 3. Fill and Save: Click or tap on the text fields to fill out the form naturally, then save your customized document securely to your device or cloud.
