Add Radio Button Choice Group - Free Online Browser Tool

Add mutually exclusive interactive radio buttons (e.g. Yes/No, Gender, Options).

A radio group is the right structure whenever a question has mutually exclusive answers — Yes/No, Male/Female, one method of payment. This tool adds them as real interactive groups, so selecting one option automatically deselects the others, which a set of loose checkboxes cannot do.

How to Use the Add Radio Button Choice Group Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the PDF

    Drop in the document that needs a choice group.

  2. Create the group

    Add a radio group and give it a name — every option in the group shares that name, which is what binds them together.

  3. Add each option

    Enter the option labels and drag each radio button into position beside its label on the page.

  4. Create and download

    The group is added as a proper AcroForm radio group. Save the form.

Frequently Asked Questions

What is the difference between a radio group and checkboxes?

Radio buttons are mutually exclusive — choosing one clears the others. Checkboxes are independent, so several can be selected at once. Use radio groups for "pick one" and checkboxes for "pick any".

Why does the group name have to be identical across options?

The shared name is what makes them one group in the PDF structure. Options with different names become independent checkboxes and will not clear each other.

Can I add a default selection?

Yes. Marking one option as the default means it is pre-selected when the form opens.

Will the group work in Adobe Acrobat?

Yes. Standard AcroForm radio groups behave exactly as expected in Acrobat and other compliant readers.

Can I make one option required?

Yes, by marking the group as required, which prevents submission until a choice has been made.
