Frequently asked questions

What forms are supported?

PDFs that already contain interactive form fields. Flat or scanned forms with no fields cannot be filled here — use Add Text or Sign instead.

Which field types can I fill?

Text boxes, checkboxes, dropdown lists, option lists, and radio button groups. Unusual or read-only fields are shown but cannot be edited.

Can I lock my answers so they cannot be changed?

Yes. Leave the flatten option on and the values are baked into the page when you download, which is what most portals and HR teams expect.

Can I sign after filling?

Yes. Download the filled form, then use Sign PDF for a visual signature stamp if needed.

Does fill-forms create new form fields?

No. It fills fields that already exist in the form.

Do I need an account?

No. Form filling is free without sign-up.
