Disable Runtime Highlights via Document JavaScripts
Use a document-level JavaScript command to automatically turn off the field highlights when the PDF is opened.
Acrobat Reader applies a default pale blue highlight to interactive form fields to help users identify fillable areas. By embedding a simple JavaScript code into the document, you can override this behavior and force the highlights to remain hidden.
Open your PDF file in Acrobat Reader. Navigate to the 'Tools' menu and select 'JavaScript'.
Click on 'Document JavaScripts' from the available options in the JavaScript toolbar.
Type a name for your script (for example, 'DisableHighlight') and click 'Add'. In the editor window, delete any default text and paste the following code: app.runtimeHighlight = false;
Click 'OK' to close the editor, then save your PDF document. The pale blue highlights will now be disabled when the file is opened.

Frequently Asked Questions
Can I disable the blue highlight for all PDFs in Acrobat Reader permanently?
Yes, you can change your personal viewer settings. Go to Edit > Preferences > Forms, and uncheck the 'Show border hover color for fields' option, or adjust the 'Fields highlight color' to match your preference.
Why do PDF form fields have a blue highlight by default?
The pale blue highlight is an accessibility and usability feature enabled by default in Acrobat Reader. It is designed to help users quickly identify which parts of a document are interactive and fillable.
Will disabling the runtime highlight affect how the form works?
No, adding the JavaScript to set app.runtimeHighlight to false only affects the visual highlight color in the PDF viewer. The form fields remain fully functional, interactive, and fillable.
