Frequently Asked Questions
Why can't I see my text field in the Fields List?
If a text field doesn't appear in the Fields List while you are in the Form Edit mode, it is not an actual form field. It is likely a hyperlink, an interactive comment text box, or a static visual element designed to look like a field.
How do I change the font size inside a fillable PDF field?
Open the field's Properties dialog by right-clicking it in the Prepare Form tool. Navigate to the 'Appearance' tab, and select your desired font size from the Text dropdown menu.
Can I make a PDF form field read-only?
Yes. Within the field's Properties dialog box, go to the 'General' tab and check the 'Read Only' box. This setting ensures that users can view the content but cannot modify it.
