Frequently Asked Questions

Can I change the required field border color for just one specific field?

Standard PDF viewers handle the 'required' highlight color globally in the application preferences. To change the border color of an individual field, you need to modify the field's specific appearance properties in the form editing mode, but the application's default required highlight may still overlay it depending on the user's software settings.

Will the red border disappear when I print the PDF form?

Yes, typically the required field highlight colors and red borders are visual aids for on-screen filling and do not appear when the document is printed. You can verify this by checking the Print Preview.

How do I completely turn off form field highlighting?

In most PDF readers, you can turn off form field highlighting by going to Edit > Preferences > Forms, and then unchecking the box that says 'Show border hover color for fields' or clicking the 'Highlight Existing Fields' toggle button on the document message bar.

Why do my form fields look different on another computer?

Form field highlight colors are controlled by the preferences of the specific PDF software viewing the file. If another user has their application set to a different required field color, the form will display according to their local settings.
