A: Hello, you can use UPDF to create fillable PDF forms. The recipient's device needs to have any PDF reader or editor installed (if not, they can use Edge browser or Google Chrome to fill out the form). Additionally, the recipient must have permission to fill out the PDF form you provide in order to complete it successfully. (In general, if you do not specifically set restrictions, the PDF form will be fillable by default.) If you have any other questions, please contact: support@superace.com. Wish you a wonderful day!
