Frequently Asked Questions
Why isn't the Format tab showing up in my PDF field properties?
The Format tab only appears for specific field types, such as Text Fields or Dropdown menus. Ensure you have selected a Text Field and not a different element like a button or checkbox.
Can I create a custom format if Social Security Number is not listed?
Yes. If your PDF editor lacks a predefined SSN format, you can select 'Custom' in the Format category and use a custom keystroke script to format the input as XXX-XX-XXXX.
Are PDF forms created in Acrobat compatible with WPS Office?
Absolutely. Standard interactive PDF forms created in Adobe Acrobat can be opened, filled out, and saved using WPS PDF without losing any interactive functionality.
