Frequently Asked Questions
Common questions regarding interactive PDF forms creation and client-side processing.
Q.What types of form fields can I create?
You can visually overlay text inputs (standard and multiline text wraps), checkbox triggers, radio button groups (for mutually exclusive choices), dropdown select menus, and digital signature boxes.
Q.Does this tool require uploading my PDF to a server?
No. All PDF loading, rendering, coordinates mapping, and field compilation occur entirely locally in your browser memory via web assembly. Your data never leaves your device.
Q.Can I customize dropdown options or radio groups?
Yes. Dropdowns support custom comma-separated list values, and radio buttons can be linked to custom radio groups to enforce mutual selection rules across multiple options.
Q.Is the output PDF compatible with standard viewers?
Yes. The output matches standard PDF AcroForm specifications and uses the NeedAppearances flag to guarantee interactive rendering inside Adobe Acrobat, web browsers, and mobile PDF readers.
